Sends a USB request on a control pipe.

The IOUSBDevRequestTO structure allows the client to specify timeout values for this request. If the request is a standard request which will change the state of the device, the device must be open, which means you should be using the IOUSBDeviceInterface for this command. Availability: This function is only available with IOUSBInterfaceInterface182 and above.

Parameter self: Pointer to the IOUSBInterfaceInterface.

Parameter pipeRef: Index of the control pipe to use. Use zero for the default control pipe on the device.

Parameter req: Pointer to an IOUSBDevRequestTO containing the request.

Returns: Returns kIOReturnSuccess if successful, kIOReturnNoDevice if there is no connection to an IOService, or kIOReturnAborted if the thread is interrupted before the call completes, kIOReturnNotOpen if the interface is not open for exclusive access.

§ControlRequestAsyncTO: Option<unsafe extern "C-unwind" fn(*mut c_void, u8, *mut IOUSBDevRequestTO, IOAsyncCallback1, *mut c_void) -> IOReturn>

Sends an asynchronous USB request on a control pipe.

The IOUSBDevRequestTO structure allows the client to specify timeout values for this request. Use pipeRef=0 for the default device control pipe. If the request is a standard request which will change the state of the device, the device must be open, which means you should be using the IOUSBDeviceInterface for this command. Availability: This function is only available with IOUSBInterfaceInterface182 and above.

Parameter self: Pointer to the IOUSBInterfaceInterface.

Parameter pipeRef: Index of the control pipe to use. Use zero for the default control pipe on the device.

Parameter req: Pointer to an IOUSBDevRequestTO containing the request.

Parameter callback: An IOAsyncCallback1 method. Upon completion, the arg0 argument of the AsyncCallback1 will contain the number of bytes that were actually transferred. A message addressed to this callback is posted to the Async port upon completion.

Parameter refCon: Arbitrary pointer which is passed as a parameter to the callback routine.

Returns: Returns kIOReturnSuccess if successful, kIOReturnNoDevice if there is no connection to an IOService, or kIOReturnNotOpen if the interface is not open for exclusive access.

§ReadPipeTO: Option<unsafe extern "C-unwind" fn(*mut c_void, u8, *mut c_void, *mut u32, u32, u32) -> IOReturn>

Performs a read on a BULK IN pipe, specifying timeout values.

The interface must be open for the pipe to exist.

If a timeout is specified and the request times out, the driver may need to resynchronize the data toggle. See

 //apple_ref/C/instm/IOUSBInterfaceInterface/ClearPipeStall/ ClearPipeStall

or

 //apple_ref/C/instm/IOUSBInterfaceInterface190/ClearPipeStallBothEnds/ ClearPipeStallBothEnds

.

Timeouts do not apply to interrupt pipes, so you should use the ReadPipe API to perform a read from an interrupt pipe. Availability: This function is only available with IOUSBInterfaceInterface182 and above.

Parameter self: Pointer to the IOUSBInterfaceInterface.

Parameter pipeRef: Index for the desired pipe (1 - GetNumEndpoints).

Parameter buf: Buffer to hold the data.

Parameter size: Pointer to the size of the buffer pointed to by buf.

Parameter noDataTimeout: Specifies a time value in milliseconds. Once the request is queued on the bus, if no data is transferred in this amount of time, the request will be aborted and returned.

Parameter completionTimeout: Specifies a time value in milliseconds. Once the request is queued on the bus, if the entire request is not completed in this amount of time, the request will be aborted and returned.

Returns: Returns kIOReturnSuccess if successful, kIOReturnNoDevice if there is no connection to an IOService, kIOReturnAborted if the thread is interrupted before the call completes, or kIOReturnNotOpen if the interface is not open for exclusive access. Returns kIOReturnBadArgument if timeout values are specified for an interrupt pipe. If an error is returned, the size parameter is not updated and the buffer will NOT contain any valid data.

§WritePipeTO: Option<unsafe extern "C-unwind" fn(*mut c_void, u8, *mut c_void, u32, u32, u32) -> IOReturn>

Performs a write on a BULK OUT pipe, with specified timeout values.

The interface must be open for the pipe to exist.

 //apple_ref/C/instm/IOUSBInterfaceInterface/ClearPipeStall/ ClearPipeStall

or

 //apple_ref/C/instm/IOUSBInterfaceInterface190/ClearPipeStallBothEnds/ ClearPipeStallBothEnds

. Availability: This function is only available with IOUSBInterfaceInterface182 and above.

Parameter self: Pointer to the IOUSBInterfaceInterface.

Parameter pipeRef: Index for the desired pipe (1 - GetNumEndpoints).

Parameter buf: Buffer to hold the data.

Parameter size: The size of the buffer pointed to by buf.

Parameter noDataTimeout: Specifies a time value in milliseconds. Once the request is queued on the bus, if no data is transferred in this amount of time, the request will be aborted and returned.

Parameter completionTimeout: Specifies a time value in milliseconds. Once the request is queued on the bus, if the entire request is not completed in this amount of time, the request will be aborted and returned.

Returns: Returns kIOReturnSuccess if successful, kIOReturnNoDevice if there is no connection to an IOService, kIOReturnAborted if the thread is interrupted before the call completes, or kIOReturnNotOpen if the interface is not open for exclusive access.

§ReadPipeAsyncTO: Option<unsafe extern "C-unwind" fn(*mut c_void, u8, *mut c_void, u32, u32, u32, IOAsyncCallback1, *mut c_void) -> IOReturn>

Performs an asynchronous read on a BULK IN pipe, with specified timeout values.

The interface must be open for the pipe to exist.

If a timeout is specified and the request times out, the driver may need to resynchronize the data toggle. See
