explain_popen_or_die - process I/O and report errors
FILE *explain_popen_or_die(const char *command, const char *flags);
The explain_popen_or_die function is used to call the popen(3) system call. On failure an explanation will be printed to stderr, obtained from explain_popen(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:
FILE *fp = explain_popen_or_die(command, flags);
