CUSERID(S) XENIX System V CUSERID(S)
Name
cuserid - Gets the login name of the user.
Syntax
#include <stdio.h>
char *cuserid (s)
char *s;
Description
cuserid returns a pointer to string which represents the
login name of the owner of the current process. If (int)s
is zero, this representation is generated in an internal
static area, the address of which is returned. If (int)s is
nonzero, s is assumed to point to an array of at least
L_cuserid characters; the representation is left in this
array. The manifest constant L_cuserid is defined in
<stdio.h>.
Diagnostics
If the login name cannot be found, cuserid returns NULL; if
s is nonzero in this case, \0 will be placed at *s.
See Also
getlogin(S), getpwent in getpwent(S)
Notes
cuserid uses getpwnam (see getpwent(S)); thus the results of
a user's call to the latter will be obliterated by a
subsequent call to the former.
