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 specified 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.

PAM_GET_AUTHTOK(3)					   BSD Library Functions Manual 					PAM_GET_AUTHTOK(3)

NAME

     pam_get_authtok -- retrieve authentication token

LIBRARY

     Pluggable Authentication Module Library (libpam, -lpam)

SYNOPSIS

     #include <sys/types.h>
     #include <security/pam_appl.h>

     int
     pam_get_authtok(pam_handle_t *pamh, int item, const char **authtok, const char *prompt);

DESCRIPTION

     The pam_get_authtok function returns the cached authentication token, or prompts the user if no token is currently cached.  Either way, a
     pointer to the authentication token is stored in the location pointed to by the authtok argument.

     The item argument must have one of the following values:

     PAM_AUTHTOK	 Returns the current authentication token, or the new token when changing authentication tokens.

     PAM_OLDAUTHTOK	 Returns the previous authentication token when changing authentication tokens.

     The prompt argument specifies a prompt to use if no token is cached.  If it is NULL, the PAM_AUTHTOK_PROMPT or PAM_OLDAUTHTOK_PROMPT item, as
     appropriate, will be used.  If that item is also NULL, a hardcoded default prompt will be used.

     If item is set to PAM_AUTHTOK and there is a non-null PAM_OLDAUTHTOK item, pam_get_authtok will ask the user to confirm the new token by
     retyping it.  If there is a mismatch, pam_get_authtok will return PAM_TRY_AGAIN.

RETURN VALUES

     The pam_get_authtok function returns one of the following values:

     [PAM_BUF_ERR]	 Memory buffer error.

     [PAM_CONV_ERR]	 Conversation failure.

     [PAM_SYSTEM_ERR]	 System error.

     [PAM_TRY_AGAIN]	 Try again.

STANDARDS

     The pam_get_authtok function is an OpenPAM extension.
