I/O Control functions

The following table describes the I/O Control functions. The name of the function ending with the letter "B" means the offset unit is byte.

Function name	Description
ForceInputBit	Writes a bit into an input of a simulated I/O module.
ForceInputByte	Writes a byte into an input of a simulated I/O module.
ForceInputDWord	Writes a double word into an input of a simulated I/O module.
ForceInputWord	Writes a word into an input of a simulated I/O module.
GetIOBuffers	Provides pointers to the input and output buffers of an I/O module.
ReadInputBit	Reads a bit from an input of a real or simulated I/O module.
ReadInputByte	Reads a byte from an input of a real or simulated I/O module.
ReadInputDWord	Reads a double word from an input of a real or simulated I/O module.
ReadInputWord	Reads a word from an input of a real or simulated I/O module.
ReadIOAlias	Reads the alias index from a real or simulated I/O module.
ReadOutputBit	Reads a bit from an output of a real or simulated I/O module.
ReadOutputByte	Reads a byte from an output of a real or simulated I/O module with a byte offset.
ReadOutputDWord	Reads a double word from an output of a real or simulated I/O module.
