  Object file - Wikipedia, the free encyclopedia
An object file format is a computer file format used for the storage of object code and related data typically produced by a compiler or assembler.
The design and/or choice of an object file format is a key part of overall system design; it affects the performance of the linker and thus programmer turnaround while developing, and if the format is used for executables, the design also affects the time programs take to begin running, and thus the responsiveness for users.
Most object file formats are structured as blocks of data all of the same sort; these blocks can be paged in as needed by the virtual memory system, needing no further processing to be ready to use.

 File format - Wikipedia, the free encyclopedia
Other file formats, however, are designed for storage of several different types of data: the GIF format supports storage of both still images and simple animations, and the QuickTime format can act as a container for many different types of multimedia.
Many file formats, including some of the most well-known file formats, have a published specification document (often with a reference implementation) that describes exactly how the data is to be encoded, and which can be used to determine whether or not a particular program treats a particular file format correctly.
Since files are seen by programs as streams of data, a method is required to determine the format of a particular file within the filesystem—an example of metadata.

For all intents and purposes, the format is the same as the NFF format, with the exception that polygonal patches must be triangles.
The SPF format is used at the United States Naval Academy as a standard graphics format for geometric data.
The UNC format was once used at the University of North Carolina as a format for geometric data in an architectural walkthrough application.

 Geomview Manual - OOGL File Formats
Typical OOGL objects begin with a key word designating object type, possibly with modifiers indicating presence of color information etc. In some formats the key word is optional, for compatibility with file formats defined elsewhere.
Sphere objects are drawn using rational Bezier patches, which are diced into meshes; their smoothness, and the time taken to draw them, depends on the setting of the dicing level, 10x10 by default.
This format is for discrete groups, such as appear in the theory of manifolds or in symmetry patterns.

Object files provide a concise and efficient representation for a compiled application, furnishing all the information needed to represent the state of the entire application at a point in time.
Object files provide a concise and efficient representation of a compiled application, and they encompass all the information needed to represent the state of the application at a point in time.
Note that in the COFF file we have just disassembled, although the format of the data in the object file is the same, the data may be represented differently.

 Object Files
To support this feature, the compilers, assembler, and linker were modified to create two-section object files, with the code in the first section and the data in the second section, and the program loader loaded the first section into a process' I space and the second into the D space.
The file page is mapped into the last page of the text segment at location 0x8004000 where the first 0x600 bytes contain the text from 0x8004000-0x80045ff, and into the data segment at 0x8005000 where the rest of the page contain the initial contents of data from 0x8005600-0x80056ff.
An object file is a sequence of 80 byte records in a common format, Figure 17.

 Sankhya Technologies - Object File Formats
Through out this seminar object file is used to refer to both an object file as well as an executable file.
An object file is often produced by one tool or system and consumed or used by a different tool or system.
The fact that an object file is produced and consumed by different tools implies that an object file should be in a standard pre-determined format for various tools to generate the object file and other tools to read and understand the contents of the object file.

 OBJCOPY
Consider the source file’s object format to be bfdname, rather than attempting to deduce it.
Use bfdname as the object format for both the input and the output file; i.e., simply transfer data from source to destination with no translation.
Set the access and modification dates of the output file to be the same as those of the input file.

 objcopy
It can write the destination object file in a format different from that of the source object file.
If the input format has an endianness (some formats do not), objcopy can only copy the inputs into file formats that have the same endian- ness or which have no endianness (e.g., srec).
Some object file formats do not permit section addresses to be changed arbitrarily.

Moving to a more explicit format allows all the special cases to be dealt with entirely in the design time environment; with all class-specific "meta data" being included as part of the class's BeanInfo.
BeanScript is a very simple file format which fulfills all of the fundamental requirements of an archive of a graph of JavaBeans.

This can be useful if you want to link together objects of different file formats with different conventions for symbol names.
This is different from --change-leading-char because it always changes the symbol name when appropriate, regardless of the object file format of the output --srec-len=val Meaningful only for srec output.

Note that this does not relocate the sections; if the program expects sec- tions to be loaded at a certain address, and this option is used to change the sections such that they are loaded at a different address, the program may fail.
You can set the contents flag for a section which does not have contents, but it is not meaningful to clear the contents flag of a section which does have contents--just remove the sec- tion instead.
This option only works on file formats which can support sections with arbi- trary names.

The Executable and Linkable Format (ELF) is a common standard in computing for executable and object code.
Other object code file formats are a.out and COFF, ELF could be considered a competitor to those, although it is generally considered to outperform both of them.
Each byte in the entire file is taken by no more than one section at a time, but there can be orphan bytes, which are not covered by a section.
