Hey ,

all these are every useful tips ,but i want to know the compatibility of the coding standards with other programs.

Recently came across the standard c conflicts,as Standard C and POSIX prohibit many kinds of extensions.

Is this statement is true .."if the extension has a significant chance of breaking any real programs or scripts, then it is not really upward compatible. So you should try to redesign its interface to make it upward compatible."

Read somewhere but still not able to understand..
