int gsasl_step64(Gsasl_session * sctx, const char * b64input, char ** b64output);


libgsasl client handle.

If this function return GSASL_OK or GSASL_NEEDS_MORE, however, the b64output buffer is allocated by this function, and it is the responsibility of caller to deallocate it by calling gsasl_free( b64output ).

Return value: Returns GSASL_OK if authenticated terminated successfully, GSASL_NEEDS_MORE if more data is needed, or error code.
