setOptions

Recursively sets option bits in the set and all child collections.

Declaration

virtual unsigned int setOptions(unsigned int options, unsigned int mask, void *context);

options:
A bitfield whose values turn the options on (1) or off (0).
mask:
A mask indicating which bits in options to change. Pass 0 to get the whole current options bitfield without changing any settings.
context:
Unused.

The options bitfield as it was before the set operation.

Kernel extensions should not call this function.

Child collections' options are changed only if the receiving set's options actually change.
