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].
