cuserid(3C) Standard C Library Functions cuserid(3C)NAMEcuserid - get character login name of the user
SYNOPSIS
#include <stdio.h>
char *cuserid(char *s);
DESCRIPTION
The cuserid() function generates a character-string representation of
the login name under which the owner of the current process is logged
in. If s is a null pointer, this representation is generated in an
internal static area whose address is returned. Otherwise, s is assumed
to point to an array of at least L_cuserid characters; the representa‐
tion is left in this array. The constant L_cuserid is defined in the
<stdio.h> header.
In multithreaded applications, the caller must always supply an array s
for the return value.
RETURN VALUES
If the login name cannot be found, cuserid() returns a null pointer.
If s is not a null pointer, the null character `\0' will be placed at
s[0].
