Determine whether or not an offscreen context is locked
int PdIsOffscreenLocked(
PdOffscreenContext_t *osc );
- osc
- A pointer to the offscreen context, as returned by
PdCreateOffscreenContext(),
that you want to check.
ph
This function tests to see if the given offscreen context is currently locked.
|
This is really only useful for debugging purposes, because the state of the
lock could potentially change between the time that
PdIsOffscreenLocked() queries the status and reports it back to
the application. |
One of:
- Pg_OSC_LOCKED
- Pg_OSC_LOCK_INVALID
- Pg_OSC_NOT_LOCKED
