+function out=RPI_waitForInterrupt(pin,timeOut)
+// Function to set a pin to wait for interrupt.
+//
+// Calling Sequence
+//  i=RPI_waitForInterrupt(pin,timeOut)
+//
+// Parameters
+//  pin    : The pin to check for interrupt. Numbering sequence to be followed as initiated using RPI_pinNumbering function.
+//  timeOut: The time (in milliseconds) for which to wait for interrupt. -1 to wait forever.
+//
+// Description
+//  When called, it will wait for an interrupt event to happen on that pin and the program will be stalled. The return value is -1 if an error occurred (and errno will be set appropriately), 0 if it timed out, or 1 on a successful interrupt event.
+//
+//  Before using RPI_waitForInterrupt, first initialise the GPIO pin and at present the only way to do this is to use the gpio program, either in a script, or using the system() call from inside the program.
+//  Eg: To wait for a falling-edge interrupt on GPIO pin 0, setup the hardware using (before running the program):
+// 	gpio edge 0 falling
+//
+// Examples
+//  i=RPI_waitForInterrupt(0,5000)
