PAM_GET_USER(3)         NetBSD 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.
