This is a very very very simple and hacky program for checking whether C/C++ header files have C++ include guards like this:
#ifdef __cplusplus
extern "C" {
#endif
and
#ifdef __cplusplus
}
#endif
It uses some very sketchy regexes to find those lines, and then if they are not present
it tries to insert them. It uses further sketchy regexes to find the normal header
include guards and inserts the __cplusplus ones inside them.
It modifies files without asking so I highly recommend you only use it on code tracked by version control. It's also pretty hacky so I suggest you at least skim the results!
Usage is trivial:
./GuardChecker <path>
It will check all files ending in .h
