cuserid(3S)                                                        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 L_cuserid characters; the representation is left in
     this array.  The constant L_cuserid 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].
