conclude()

virtual void dxd::kmdf::client::conclude ( )

inlineprotectedvirtual

virtual user client deinitialization method

virtual conclude() gets called by the dynax driver framework when an applications closes its user client interface to the device.

ioctl()

os_result dxd::kmdf::client::ioctl ( unsigned int ioctl, const void * in, size_t size_in, void * out, size_t size_out, size_t & size )

virtual user client I/O control handler

virtual ioctl() gets called by the dynax driver framework when an applications issues IOCTL request to its user client interface.

Parameters

ioctl	IOCTL
in	buffer pointer containing data from user mode
size_in	size of the buffer containing data from user mode
out	buffer pointer accepting data to be returned to user mode
size_out	size of the buffer accepting data to be returned to user mode
size	actual size of data to be returned to user mode
