NAME
|
|
cuserid - get character login name of the user
|
|
SYNTAX
|
|
#include <stdio.h>
|
|
char *cuserid (s)
|
|
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.
|
|
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].
