int gsasl_callback(Gsasl * ctx, Gsasl_session * sctx, Gsasl_property prop);
Gsasl * ctx
handle received from gsasl_init(), may be NULL to derive it
Gsasl_session * sctx
enumerated value of Gsasl_property type.
Invoke the application callback. The prop value indicate what the
callback is expected to do. For example, for
GSASL_ANONYMOUS_TOKEN, the function is expected to invoke
gsasl_property_set(SCTX, GSASL_ANONYMOUS_TOKEN, "token") where
"token" is the anonymous token the application wishes the SASL
mechanism to use. See the manual for the meaning of all
Note that if no callback has been set by the application, but the
obsolete callback interface has been used, this function will
translate the old callback interface into the new. This interface
should be sufficient to invoke all callbacks, both new and old.
Returns whatever the application callback return, or
GSASL_NO_CALLBACK if no application was known.
