Just as an addition - this call sets up the file handles limit from OS/2's
point of view, but many (most?) C compiler libraries also have an internal
file handle limit that might or might not be fixed.

So - increasing the file handles this way definitely works as long as you
use OS/2 filesystem calls to open and access the extra handles.

Alternatively, another method that I've used successfully in the past is to
use the C library file calls for files that I really needed C functions to
access, and use the OS/2 calls for all the others.  The applicability of this
method is application-dependent, but as long as the number of files you
access through C library routines remains small enough, you can still get
to a lot of files with the OS/2 calls.
