U2C_IoRead

The U2C_IoRead function obtains the value of the GPIO port pins.

Parameters:

	hDevice	Handle to the U2C-12 device.
	pValue	A pointer to unsigned long to be filled with the value of the GPIO pins. pValue is treated as unsigned long 0xXXCCBBAA, where CC, BB and AA correspond to the C, B and A port pins: AA bits 7..0 correspond to Port A pins 7..0 BB bits 7..0 correspond to Port B pins 7..0 CC bits 7..0 correspond to Port C pins 7..0 XX bits 7..0 reserved

Return values:

	U2C_SUCCESS	The GPIO pins state was successfully read.
	U2C_HARDWARE_NOT_FOUND	U2C-12 device referenced by hDevice handle was not found.
