CUSERID(3S-POSIX)   RISC/os Reference Manual    CUSERID(3S-POSIX)



NAME
     cuserid - get character string associated with the effective
     user ID

SYNOPSIS
     #include <stdio.h>

     char *cuserid (s)
     char *s;

DESCRIPTION
     cuserid generates a character-string representation of the
     name associated with the effective user ID of the process.
     If s is a NULL pointer, this representation is generated in
     an internal static area, the address of which is returned.
     Otherwise, s is assumed to point to an array of at least
     Lcuserid characters; the representation is left in this
     array.  The constant Lcuserid is defined in the <stdio.h>
     header file.

DIAGNOSTICS
     If the name cannot be found, cuserid returns a NULL pointer;
     if s is not a NULL pointer, a null character ('\0') will be
     placed at s[0].
