int sasl_client_init(const sasl_callback_t *callbacks);
sasl_client_init() initializes SASL. It must be called before any calls to sasl_client_start. This call initializes all SASL client drivers (e.g. authentication mechanisms). These are usually found in the /usr/lib/sasl2 directory but the directory may be overridden with the SASL_PATH environment variable.
callbacks specifies the base callbacks for all client connections. See the sasl_callbacks man page for more information
RETURN VALUEsasl_client_init returns an integer which corresponds to one of the following codes. SASL_OK is the only one that indicates success. All others indicate errors and should either be handled or the authentication session should be quit.
