Topic: Standard output


  
  CLHS: Variable *DEBUG-IO*, *ERROR-OUTPUT*...
The value of *standard-input*, called standard input, is a stream that is used by many operators as a default source of input when no specific input stream is explicitly supplied.
The value of *standard-output*, called standard output, is a stream that is used by many operators as a default destination for output when no specific output stream is explicitly supplied.
The value of *trace-output*, called trace output, is the stream on which traced functions (see trace) and the time macro print their output.

 Standard Input, Standard Output, and Standard Error
In addition to the standard input and standard output, commands often produce other types of output, such as error or status messages known as diagnostic output.
In the example, the output of the ls command is the input for the pg command.
In the example, the output of the ls command is the input for the grep command.

 Standard streams - Wikipedia, the free encyclopedia
These standard connections are provided in Unix and Unix-like operating systems, C and C++ runtime environments, and their successors.
Standard output is the stream where a program writes its output data.
Standard error is another output stream typically used by programs to output error messages or diagnostics.

 Help: Redirection
Redirection can be used to reassign the standard input (stdin), standard output (stdout), and standard error (stderr) devices from their default settings (the keyboard and screen) to another device such as the printer or serial port, to a file, or to the Windows clipboard.
You cannot redirect all output from the execution of a DO loop due to the restriction that the DO command and its matching ENDDO may not be part of a command group.
Output redirection on a command within the batch file will take effect for that command only; when the command is completed, output will revert to the redirected output file or device in use for the batch file as a whole.

 Standard output - Linux 101   (Site not responding. Last check: 2007-10-07)
Standard input, or stdin, is simply your stream of characters that you type in on your keyboard that are to be sent to the program.
Standard output, or stdout, is the name of the default output stream that all console applications have.
This output is sent by default directly to the console, and is the program's output.

 LinuxDevCenter.com -- Using Standard Input and Output
[1] Likewise, if a program's output consists entirely of alphanumeric characters and punctuation, there is no difference between writing to a file, writing to a terminal, and writing to the input of another program (as in a pipe).
While standard I/O is a basic feature of UNIX, the syntax used to redirect standard I/O depends on the shell you are using.
But standard I/O is the glue that allows you to make big programs out of smaller ones, and is therefore a crucial part of the operating system.

 The Standard Output Stream   (Site not responding. Last check: 2007-10-07)
The standard output stream is a C library concept that has been assimilated into the Java language.
Simply put, a stream is a flowing buffer of characters; the standard output stream is a stream that writes its contents to the display.
The standard output stream is a convenient place for an old-fashioned text-based application to display its output.

 Standard Output Definition
Standard output can be redirected from the screen to a file where it is written and saved, to a printer where it is printed, or to another program where it is used as an input.
To carry the example further, the standard output of grep could be redirected from the monitor to a file or to another program.
The input counterpart of standard output is standard input.

 Linux.com - What are standard input and standard output?
Your keyboard is your "standard input" (stdin) device, and the screen is the "standard output" (stdout) device.
The standard output, for example, on a heavily monitored server in a large environment may be a printer.
Output of one command can be piped into another command virtually as many times as you want, just as long as these commands would normally read input from standard input and write output to the standard output.

 Standard IO Applications | Palm OS® Programmer's Companion
A standard IO provider application is necessary to execute and see output from a standard IO application.
Standard IO applications can use several input and output functions that mimic their similarly named UNIX counterparts.
To handle input and output, the standard IO provider application must provide a form with a text field and a scroll bar.

 Output
Output types may be sent to standard output or to named files, which Nmap can append to or clobber.
XML output is one of the most important output types, as it can be converted to HTML, easily parsed by programs such as Nmap graphical user interfaces, or imported into databases.
Output customization is normally done after the scan using tools such as grep, awk, and Perl, but this feature was added due to overwhelming requests.

This output can either be a document generated by the script, or instructions to the server for retrieving the desired output.
Normally, scripts produce output which is interpreted and sent back to the client.
Some scripts may want to avoid the extra overhead of the server parsing their output, and talk directly to the client.

 Standard IO | Palm OS® Programmer's API Reference
An output stream to which to write the formatted output.
This routine is useful for registering a command that is inside the standard IO provider application instead of in its own database.
This function must be called from the form event handler before it does its own processing with any of the objects unrelated to standard IO in the form.

 C++ I/O
To remember which is the input operator and which is the output operator, think of the angle brackets as pointing in the direction the values are flowing; for example, when you write the value of x using "cout << x", the brackets point to cout (so the value is going from x to cout).
It is often useful to write a function that takes an input stream or an output stream as a parameter, and reads from or writes to the given stream (without worrying about whether it is using the standard input/output or a particular file).
A call to function f can pass either the standard input or a file (an ifstream) as the first parameter, and can pass either the standard output, the standard error, or a file (an ofstream) as the second parameter.

 PRINTF - formatted output to standard output.
Note also that the standard rules for passing arguments in a variable argument list automatically convert "char" and "short" values to "int", and "float" values to "double", so "char", "short", and "float" arguments are not possible.
"int" argument is output as an unsigned integer written with hexadecimal digits, using the letters 'a' to 'f' for hex digits greater than 9.
If the output value is shorter than the given width, it is padded to the appropriate width by putting blanks on the right (or on the left, if the '-' "modifier" character is specified).

 The ins and outs of standard input/output - Java World
Standard I/O is a standardized input/output mechanism that originates from the Unix operating system.
Although this mechanism is mostly used with older non-GUI operating systems, standard I/O still plays a role in modern GUI (graphical user interface) operating systems, where people use it to debug malfunctioning programs and to teach input/output in entry-level programming courses.
The standard input device is that part of the operating system that controls from where a program receives its input.

 [No title]
Whatever you type (or paste) into the fl window becomes standard input to the console application and whatever text you see displayed is actually the standard output and/or standard error (it can be difficult to tell them apart sometimes).
This becomes very interesting when you consider that standard input and output are really compatible ideas and that standard output from one program can serve as standard input to another, and so on and on.
This represents the command-line parameters passed to the console application (unlike with standard C applications, the name of the executable is not passed to the application as the first argument).

 Standard Input and Output in Java by Richard G Baldwin
What is standard I/O? The standard input and standard output stream notion is based on the concept of working on a system that has a standard input device and a standard output device.
Likewise, the default standard output device is the screen, but it can be redirected at the operating system level to another device.
This is a DOS command that redirects the standard output to a device other than the screen: namely to a disk file.

 10.2. Standard input, output, and error
UNIX users are already familiar with the concept of standard input, standard output, and standard error.
Since it is so common to write error messages to standard error, there is a shorthand syntax that can be used instead of going through the hassle of redirecting it outright.
Standard input, on the other hand, is a read-only file object, and it represents the data flowing into the program from some previous program.

 Smitha Papolu - Final Input-Output Page
The standard output provides a means for the program to output data.
The standard error is where the program reports any errors encountered during execution.
Redirecting standard error is a bit trickier, depending on the kind of shell you're using (there's more than one flavor of shell program!).

 Intro to File Input/Output in C
One way to get input into a program or to display output from a program is to use standard input and standard output, respectively.
Remember that standard input is normally associated with the keyboard and standard output with the screen, unless redirection is used.
Standard error is normally associated with the same place as standard output; however, redirecting standard output does not redirect standard error.

 The Standard I/O Streams
The concept of standard input and output streams is a C library concept that has been assimilated into the Java environment.
Probably the most often used items from the System class are the the standard output and standard error streams, which you can use to display text to the user.
The standard output stream is typically used for command output, that is, to display the results of a command to the user.

 How to spawn console processes with redirected standard handles
This article describes how to redirect the input and output of a child process that receives input from the standard input handle or sends output to the standard output handle.
The handles must be inheritable and the CreateProcess() API must specify that inheritable handles are to be inherited by the child process by specifying TRUE in the bInheritHandles parameter.
As a result, the output to the redirection pipe of a printf() call or the input from a getch() call is not flushed immediately and delays, sometimes-infinite delays occur.
