		uint32_t	cap
	)

Check for a capability.

The capabilities are expected to be stored in a bit array consisting of one or more bytes where each individual bit represents a capability. The first bit of this array is the least significant bit of the first byte and the following bits are sequentially numbered in order of increasing bit significance and byte index. A set bit indicates a supported capability.

Parameters
