explain_fork_or_die - create a child process and report errors

#include <libexplain/fork.h>

void explain_fork_or_die(void);

The explain_fork_or_die function is used to call the fork(2) system call. On failure an explanation will be printed to stderr, obtained from explain_fork(3), and then the process terminates by calling exit(EXIT_FAILURE).

This function is intended to be used in a fashion similar to the following example:

explain_fork_or_die();
This function only returns on success. On failure, prints an explanation and exits.

fork(2)
create a child process
explain_fork(3)
explain fork(2) errors
exit(2)
terminate the calling process
