LIBRARY
Pluggable Authentication Module Library (libpam, -lpam)
SYNOPSIS
#include <sys/types.h>
#include <security/pam_appl.h>
int
pam_get_user(pam_handle_t *pamh, const char **user, const char *prompt);
DESCRIPTION
The pam_get_user function returns the name of the target user, as speci-
fied to pam_start(3). If no user was specified, nor set using
pam_set_item(3), pam_get_user will prompt for a user name. Either way, a
pointer to the user name is stored in the location pointed to by the user
argument.
The prompt argument specifies a prompt to use if no user name is cached.
If it is NULL, the PAM_USER_PROMPT will be used. If that item is also
NULL, a hardcoded default prompt will be used.
RETURN VALUES
The pam_get_user function returns one of the following values:
[PAM_BUF_ERR] Memory buffer error.
[PAM_CONV_ERR] Conversation failure.
[PAM_SYSTEM_ERR] System error.
