check_fork

Invoke fork() during a test and assign the child to the same process group that the rest of the test case uses.

One can invoke fork() directly during a test; however doing so may not guarantee that any children processes are destroyed once the test finishes. Once a test has completed, all processes in the process group will be killed; using this wrapper will prevent orphan processes.

If Check is compiled without fork() support this call simply return -1 and does nothing.

Returns:

On success, the PID of the child process is returned in the parent, and 0 is returned in the child. On failure, a value of -1 is returned to the parent process and no child process is created.

Since:
