| | Interoperability of 32- and 64-bit applications on 64-bit HP-UX - HP Dev Resource Central |
 | | For 32-bit applications running on 64-bit HP-UX to communicate correctly with the operating system and with 64-bit applications, it is necessary to create an environment where both types of applications can exchange information with no loss of data or accuracy, and share resources in a way that optimizes the performance of each application. |
 | | When a 64-bit application shares a memory segment with a 32-bit application, and if the 64-bit application created the shared memory segment, the application must tell the system to use 32-bit addressing to map that shared memory segment. |
 | | Therefore, if a 64-bit application is used to create a memory-mapped file with the intention of sharing it with 32-bit applications, it must inform the system so that the system uses 32-bit virtual addressing. |
