cuserid



PURPOSE

Gets the alphanumeric user name associated with the current process.

LIBRARY

Standard I/O Library (libc.a)

SYNTAX

#include <stdio.h>

char *cuserid (s)
char *s;

DESCRIPTION

The cuserid subroutine generates a character string representing the user name
of the owner of the current process.

If the s parameter is a NULL pointer, then the character string is stored into
an internal static area, the address of which is returned.

If the s parameter is not a NULL pointer, then the character string is stored
into the array pointed to by the s parameter.  This array must contain at least
L_cuserid characters.  L_cuserid is a constant defined in the stdio.h header
file.

If the user name cannot be found, the cuserid subroutine returns a NULL
pointer; if the s parameter is not a NULL pointer, then a null character
("'\0'") is stored into s[0].
