NetBSD 6.1.5 - man page for pam_get_item (netbsd section 3)

PAM_GET_ITEM(3) 		   BSD Library Functions Manual 		  PAM_GET_ITEM(3)

NAME
     pam_get_item -- get PAM information

LIBRARY
     Pluggable Authentication Module Library (libpam, -lpam)

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

     int
     pam_get_item(const pam_handle_t *pamh, int item_type, const void **item);

DESCRIPTION
     The pam_get_item function stores a pointer to the item specified by the item_type argument
     in the location pointed to by the item argument.  The item is retrieved from the PAM context
     specified by the pamh argument.  If pam_get_item fails, the item argument is untouched.

     The following item types are recognized:

     PAM_SERVICE	 The name of the requesting service.

     PAM_USER		 The name of the user the application is trying to authenticate.

     PAM_TTY		 The name of the current terminal.

     PAM_RHOST		 The name of the applicant's host.

     PAM_CONV		 A struct pam_conv describing the current conversation function.

     PAM_AUTHTOK	 The current authentication token.

     PAM_OLDAUTHTOK	 The expired authentication token.

     PAM_RUSER		 The name of the applicant.

     PAM_USER_PROMPT	 The prompt to use when asking the applicant for a user name to authenti-
			 cate as.

     PAM_AUTHTOK_PROMPT  The prompt to use when asking the applicant for an authentication token.

     PAM_OLDAUTHTOK_PROMPT
			 The prompt to use when asking the applicant for an expired authentica-
			 tion token prior to changing it.

     PAM_HOST		 The name of the host the application runs on.

     PAM_SOCKADDR	 The sockaddr_storage of the applicants's host.

     PAM_NUSER		 The ``nested'' user if this is a login on top of a previous one.

     See pam_start(3) for a description of struct pam_conv.

RETURN VALUES
     The pam_get_item function returns one of the following values:

     [PAM_SYMBOL_ERR]	 Invalid symbol.

     [PAM_SYSTEM_ERR]	 System error.
