PAM_GET_USER(3)		 BSD Library Functions Manual	       PAM_GET_USER(3)

NAME
     pam_get_user -- retrieve user name

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.
