Macro Definition Documentation

#define check	(		rc,
			msg
	)

If rc is fail, writes an error message and exits. The error message contains the file name and the line number of the source code in a standard from, which makes it possible to go there using good source browsers like e.g. emacs.

For example

check(0==1,"This is obviously false.");

will print something like this (and then exits).

file_name.cc:123: error: This is obviously false.
