Common IOCTLs

The following IOCTLs are common to all device profiles.

#define RTIOC_DEVICE_INFO   _IOR(RTIOC_TYPE_COMMON, 0x00, struct rtdm_device_info)
 Retrieve information about a device or socket. More...
 
#define RTIOC_PURGE   _IOW(RTIOC_TYPE_COMMON, 0x10, int)
 Purge internal device or socket buffers. More...
 

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.

Macro Definition Documentation
