NAME

pam_get_data — get module information

LIBRARY

Pluggable Authentication Module Library (libpam, -lpam)

SYNOPSIS

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

int
pam_get_data(const pam_handle_t *pamh, const char *module_data_name, const void **data);

DESCRIPTION

The pam_get_data function looks up the opaque object associated with the string specified by the module_data_name argument, in the PAM context specified by the pamh argument. A pointer to the object is stored in the location pointed to by the data argument. If pam_get_data fails, the data argument is untouched.

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

RETURN VALUES

The pam_get_data function returns one of the following values:

[PAM_NO_MODULE_DATA]

Module data not found.

[PAM_SYSTEM_ERR]

System error.
