void ace_clearerr_helper ( FILE *  stream ) [inline]
char* ace_cuserid ( char *  user ) [inline]

Helper for the ACE_OS::cuserid() function.

On some platforms cuserid is a macro. Defining ACE_OS::cuserid() becomes really hard, as there is no way to save the macro definition using the pre-processor. This inline function achieves the same effect, without namespace pollution or performance penalties.

We maybe should move a lot of the code in ACE_OS::cuserid here so it is treated the same as the above ace_difftime and ace_timezone. But since there is a good deal more code in ACE_OS::cuserid, we probably need to move some of it off into some sort of emulation function.
