Control Program Function Calls
This section reflects the Dos API interface of OS/2 only.
The Dos function calls can be used in full-screen and Presentation Manager sessions to perform basic operating-system operations, such as file input/output, memory allocation, and thread and process creation/control/communication.
Notes:
- Calls marked xPM are not supported by Presentation Manager, and must not be used by Presentation Manager applications. An error code is returned if any of these calls are issued.
- Calls marked xWPM are not windowable and are not supported by Presentation Manager. They can be used in OS/2 mode.
- Calls marked FAPI are present in the Family API.
