CNdisApi::DeviceIoControl
BOOL
DeviceIoControl (DWORD dwService, void
*BuffIn, int
SizeIn, void *BuffOut,
int SizeOut, int
*SizeRet = NULL, LPOVERLAPPED
povlp = NULL);
Return Value:
TRUE if request
succeeded, FALSE otherwise
Parameters:
dwService
Specifies IOCTL to
pass to the helper driver.
BuffIn
Specifies the input
buffer pointer.
SizeIn
Specifies the size of
input buffer.
BuffOut
Specifies the output
buffer pointer.
SizeOut
Specifies the size of
output buffer.
SizeRet
Specifies the
optional parameter to save number of bytes returned by
DeviceIoControl call.
povlp
Specifies the pointer
