pam_set_data — set module information

Pluggable Authentication Module Library (libpam, -lpam)

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

int
pam_set_data(pam_handle_t *pamh, const char *module_data_name, void *data, void (*cleanup)(pam_handle_t *pamh, void *data, int pam_end_status));

The pam_set_data function associates a pointer to an opaque object with an arbitrary string specified by the module_data_name argument, in the PAM context specified by the pamh argument.

If not NULL, the cleanup argument should point to a function responsible for releasing the resources associated with the object.

This function and its counterpart pam_get_data(3) are useful for managing data that are meaningful only to a particular service module.

The pam_set_data function returns one of the following values:

[PAM_BUF_ERR]
Memory buffer error.
[PAM_SYSTEM_ERR]
System error.

pam(3), pam_get_data(3), pam_strerror(3)

X/Open Single Sign-On Service (XSSO) - Pluggable Authentication Modules, June 1997.

The pam_set_data function and this manual page were developed for the FreeBSD Project by ThinkSec AS and Network Associates Laboratories, the Security Research Division of Network Associates, Inc. under DARPA/SPAWAR contract N66001-01-C-8035 (“CBOSS”), as part of the DARPA CHATS research program.
