NAME

       explain_open_or_die - open file and report errors

SYNOPSIS

       #include <fcntl.h>
       #include <libexplain/open.h>

       int explain_open_or_die(const char *pathname, int flags, int mode);

DESCRIPTION

       Given  a  pathname for a file, open() returns a file descriptor, a small, non‐negative integer for use in
       subsequent system calls (read(2), write(2), lseek(2), fcntl(2), etc.).  The file descriptor returned by a
       successful  call  will  be  the  lowest‐numbered file descriptor not currently open for the process.  See
       open(2) for more information.

RETURN VALUE

       On success, the new file descriptor is returned.

       On error, a description of the error is obtained via explain_open(3), and printed on stderr.  The process
       is the terminated via a call to the exit(EXIT_FAILURE) function.
