Determine if a piece of code exits the program with MSVC

Question

On a Gnu system, I can write a C macro like dies_ok() that will fork a new process, run a piece of code, after which it can write to a shared piece of memory that it didn't exit, then in the parent process I can determine if it exited or not. This is useful for tests:

dies_ok({int x = 0/0;}, "can't divide by zero");
lives_ok({int x = 3/7;}, "this is a perfectly fine statement");
dies_ok({abort();}, "abort kills the program");

Is there any way to accomplish this on MSVC where there isn't a fork function?

EDIT: Heres the implementation that works on linux with gcc: http://github.com/zorgnax/libtap/blob/master/tap.h

Answer 1

CreateProcess is like fork()/exec()

The BOOST library has shared memory support for msvc. You can also use the Windows atom table which is native to Windows- see msdn for

Q: I don't get why in unix you have to write a string to shared memory. You can simply call exit(n) from the child process where n is an index into a predefined char *p[] list of error codes or success codes. You can have an array of 255 values, excluding 0 for EXIT_SUCCESS. Or read the sysexits.h header file for another set of ideas. wait() or waitpid() will return the exit code, or determine if the process did not exit
