- the realm acquisition callback function
cc [ flag ... ] file ... -lsasl [ library ... ] #include <sasl/sasl.h> int sasl_getrealm_t(void *context, int id, const char **availrealms, const char **result);
Use the sasl_getrealm_t() functionwhen there is an interaction with SASL_CB_GETREALM as the type.
If a mechanism would use this callback, but it is not present, then the first realm listed is automatically selected. A mechanism can still force the existence of a getrealm callback by SASL_CB_GETREALM to its required_prompts list.
