RxUsbIrqWrite

Description
Executes synchronous host-to-device Interrupt Transfer with a specific endpoint.

Syntax
rc = RxUsbIrqWrite(Handle,Endpoint,AltSetting,NumBytes,Data,Timeout)

Parameters

 * Handle : the Device Handle received from the previous RxUsbOpen.


 * Endpoint : the Endpoint Number with the Direction Bit set to zero.


 * AltSetting : the Alternate Setting of the interface having this endpoint.


 * NumBytes : the name of the variable to receive the number of bytes transferred.


 * Data : the character string if any with the data bytes to be transferred.


 * Timeout : the timeout to wait for completion in milliseconds.

Return Code
0x0000 - NO_ERROR

Example Code
/* add RxUsbIrqWrite */ rc = RxFuncAdd('RxUsbIrqWrite','usbcalls','RxUsbIrqWrite') say '+RxUsbIrqWrite,RC=0x'd2x(rc)

/* invoke RxUsbIrqWrite */ drop NumBytes /* receives number of data bytes written */ Endpoint=2; AltSetting=0; Data=copies(x2c(DB),4096); Timeout=8000 rc = RxUsbIrqWrite(Handle,Endpoint,AltSetting,NumBytes,Data,Timeout) say '*RxUsbIrqWrite,RC=0x'd2x(rc)

/* drop RxUsbIrqWrite */ rc = RxFuncDrop('RxUsbIrqWrite') say '-RxUsbIrqWrite,RC=0x'd2x(rc)
