Looks like you're trying to port a C program from Unix.  Which program and
from what flavor of Unix?

MPE does not support any of these unresolved externals in POSIX.

How Apache deals with this:

#ifdef NEED_STRDUP
char *strdup (const char *str)
{
  char *dup;

  if(!(dup = (char *)malloc (strlen (str) + 1)))
      return NULL;
  dup = strcpy (dup, str);

  return dup;
}
#endif

Shouldn't be too hard to generate a unique filename on your own without this.

Process groups aren't supported at all by MPE.  Just comment out this call.

These should all be doable via the intrinsics FCONTROL and FDEVICECONTROL.

Try and use another time function....

I've never heard of these.

You're out of luck here, since the concepts of file systems and mount points
does not exist in MPE.

There is no such thing as utmp in MPE POSIX.

Never heard of these.
