Method GSSAPI.Context()->required_services()

Method required_services

int required_services(void|int services)

Description

Gets and optionally sets the set of services that must be provided in the context. The returned and given value is a bitfield of the GSSAPI.*_FLAG constants.

This is mainly useful to change the per-message service flags that verify_mic and unwrap use to decide whether a condition is an error or not.

Parameter services

New set of required services. If this is not given then the set is not changed.

If the context is established and services contain a service which isn't currently provided then the context is closed and a GSSAPI.MissingServicesError is thrown immediately.

GSSAPI.PROT_READY_FLAG is ignored in this parameter.

Returns

Returns the current set of required services (after setting them to services, if provided).
