explain_fopen_or_die(3) FreeBSD Library Functions Manual explain_fopen_or_die(3)

explain_fopen_or_die - open file and report errors

#include <libexplain/fopen.h>
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.
This is a quick and simple way for programs to constitently report file open errors in a consistent and detailed fahion.

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 exit(EXIT_FAILURE).
