Strange behaviour of exit()!! (Read 811 times)

Strange behaviour of exit()!!
Oct 8th, 2007, 2:37am  
Hi,
I'm a C++ Programmer with a slight knowledge of Java. I'm using Processing for past 2 months but used this exit() function for the first time - and am surprised to see its strange behaviour - it exits from the program only after the draw function executes completely!! That means, if we are using this in a while() block, and if we write exit() in it, it will have no effect at all !!

Do we have any other function which is same as the normal exit() function which exits just when we write it?

this behavior is clearly stated in the reference:
http://processing.org/reference/exit_.html

unlike a c++ program, a processing sketch cannot simply terminate in the middle of a draw(), it could easily crash your system if you're using opengl or that sort of thing.

to force termination, you can use java's System.exit(0), but this would be bad style anyway (and leave you subject to potential crashing).

Thanks. For some bad reason, I need to use this System.exit(0) only Smiley
