NAME
cuserid —
LIBRARY
Compatibility Library (libcompat, -lcompat)SYNOPSIS
#include <stdio.h>
char *
cuserid(char
*s);
DESCRIPTION
cuserid() function is made
obsolete by
getpwuid(3).The function cuserid() gets the user name
associated with the effective UID of the current process. If the argument
s is non-NULL, the name is copied to the buffer it
points to, and that address is being returned. This buffer must provide
space for at least L_cuserid characters. The L_cuserid
constant is defined in
<stdio.h>.
If s is NULL, an internal array is used and its address will be returned.
RETURN VALUES
Thecuserid() function returns the address of an array
in which the name has been stored.
If the name associated with the effective UID of the current process could not be found, either a null pointer will be returned, or (if s is non-NULL) the buffer s will be filled with a null string.
