NAME

pam_get_item — get PAM information

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 authenticate 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 authentication token prior to changing it.
PAM_HOST: The name of the host the application runs on.

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