explain_fdopen_or_die - stream open functions and report errors
void explain_fdopen_or_die(int fd, const char *mode);
The explain_fdopen_or_die function is used to call the fdopen(3) system call. On failure an explanation will be printed to stderr, obtained from explain_fdopen(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_fdopen_or_die(fd, mode);
