+function out=RPI_getAlt(pin)
+// Function to get the current mode of pin
+//
+// Calling Sequence
+//  s=RPI_getAlt(pin)
+//
+// Parameters
+//  pin: The pin number to read the voltage from. Numbering sequence to be followed as initiated using RPI_pinNumbering function.
+//
+// Description
+//  This function returns the current mode of the pin. Output will be 0 for INPUT, 1 for OUTPUT, 2 for PWM_OUT and 3 for CLOCK.
+//
+// Examples
+//  s=RPI_getAlt(0)
