Question:

What are the differences between DOSCALLS.LIB, OS2.LIB, and API.LIB?

Response:

DOSCALLS.LIB has the OS/2 Version 1.00 systems calls in it.

OS2.LIB is a superset of DOSCALLS.LIB, this library came with the
OS/2 SDK not with the retail version of C 5.1. It has the OS/2
Version 1.10 systems calls in it (PM calls have been added to the
OS/2 Version 1.00 calls).

API.LIB is the library used for programs that are going to be bound to
run in both OS/2 and DOS. They are the FAPI ( Family API) routines.

You can use OS2.LIB in place of DOSCALLS.LIB because it contains all
of the routines. Only use API.LIB if you are binding.
