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.
