PAM_GET_DATA(3) Linux-PAM Manual PAM_GET_DATA(3)
pam_get_data - get module internal data
#include <security/pam_modules.h> int pam_get_data(const pam_handle_t *pamh, const char *module_data_name, const void **data);
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.
PAM_SUCCESS Data was successful retrieved. PAM_SYSTEM_ERR A NULL pointer was submitted as PAM handle or the function was called by an application. PAM_NO_MODULE_DATA Module data not found or there is an entry, but it has the value NULL.
