clockid_t

clock_id

)

Follow POSIX or FACE Technical Standard on timer_create.

POSIX allows for the creation of timers based on CLOCK_REALTIME. This is viewed as a safety issue by the FACE Technical Standard and required to return an error. These are conflicting behaviors. This method is instanced by configuration when FACE conformant behavior is desired by the application.

Parameters

[in]

clock_id

is the clock ID to validate

Returns

0 if clock_id is allowed for use. Otherwise an errno value.
