Error code 3021

By error code I assume you mean errno, and in that case errno 3021
would map to message CPE3021: The value specified for the argument
is not correct.

In looking at your sample code, I would suggest a few changes.  I
would add VALUE to the three parameters being defined on your function
prototype of fcntl(); verify that F_SETFL is being initialized to the
value you want (looking at qsysinc/h fcntl it looks like SETFL is
mapped to '7' and that '4' is SETLK); verify your flag setting is
appropriate for what your arg is (O_NONBLOCK is not a 4 for instance);
etc.
