explain_fopen_or_die — open file and report errors
FILE *explain_fopen_or_die(const char *pathname, const char *flags);
The explain_fopen_or_die() function opens the file whose name is the string pointed to by pathname and associates a stream with it. See fopen(3) for more information.

Upon successful completion explain_fopen_or_die returns a FILE pointer.
If an error occurs, explain_fopen will be called to explain the error, which will be printed onto stderr, and then the process will terminate by calling
stream open functions

terminate the calling process
