sasl_dispose(3) -- Linux man page
NAMEsasl_dispose - Dispose of a SASL connection object
#include <sasl/sasl.h> void sasl_dispose(sasl_conn_t **pconn );
sasl_dispose is called when a SASL connection object is no longer needed. Note that this is usually when the protocol session is done NOT when the authentication is done since a security layer may have been negotiated.
