cuserid(3S)            UNIX System V(C Development Set)             cuserid(3S)


NAME
      cuserid - get character login name of the user

SYNOPSIS
      #include <stdio.h>

      char *cuserid (char *s);

DESCRIPTION
      cuserid generates a character-string representation of the login name
      that the owner of the current process is logged in under.  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.

SEE ALSO
      getlogin(3C), getpwent(3C).

DIAGNOSTICS
      If the login 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].
