cc [ flag ... ] file ... -lsasl [ library ... ] #include <sasl/sasl.h> int sasl_getsimple_t(void *context, int id, const char **result, unsigned *len);
Use the sasl_getsimple_t() callback function to retrieve simple data from the application such as the authentication name, the authorization name, and the realm. The id parameter indicates which value is requested.
The context from the callback structure.

To cancel user, set the value of result with a null-terminated string. If the value of result is NULL, then the user is cancelled.
