pam_get_data 3 Linux-PAM Manual 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_data3 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. pam_end3 , pam_set_data3 , pam_strerror3
