Синопсис (Synopsis)

#include <security/pam_modules.h>

       int pam_get_data(const pam_handle_t *pamh,

                        const void **data);

Описание (Description)

This function together with the pam_set_data(3) function is
       useful to manage module-specific data meaningful only to the
       calling PAM module.

       The pam_get_data function looks up the object associated with the
       (hopefully) unique string module_data_name in the PAM context
       specified by the pamh argument. A successful call to pam_get_data
       will result in data pointing to the object. Note, this data is
       not a copy and should be treated as constant by the module.
