NAME
pam_get_data - get module internal dataSYNOPSIS
#include <security/pam_modules.h>
- int pam_get_data(const pam_handle_t *pamh, const char *module_data_name, const void **data);
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.
RETURN VALUES
- 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.
