	Retrieve information about a device or socket.
#define	RTIOC_PURGE   _IOW(RTIOC_TYPE_COMMON, 0x10, int)
	Purge internal device or socket buffers.

Detailed Description

Device profiles define which operation handlers a driver of a certain class has to implement, which name or protocol it has to register, which IOCTLs it has to provide, and further details. Sub-classes can be defined in order to extend a device profile with more hardware-specific functions.
