Re: ISR Syntax.

Please help some one by telling syntax for ISR routines like GPIO interrupts etc..
Also kindly where the source files are there so that i am not able to find all function definitions in the example codes.

google attachInterrupt to start

google pinChangeInterrupt to continue

All of the source files are in the folder where you installed the IDE.

Syntax is the same for any C function, but there are some obvious limitations.
An ISR takes no arguments and returns no values.

Nick Gammon has a good tutorial about interrupts.
