SYNOPSIS

10       void explain_fdopen_or_die(int fd, const char *mode);

DESCRIPTION

13       The explain_fdopen_or_die function is used to call the fdopen(3) system
14       call.  On failure an explanation will be printed  to  stderr,  obtained
15       from  explain_fdopen(3),  and  then  the  process terminates by calling
16       exit(EXIT_FAILURE).
17
18       This function is intended to be used in a fashion similar to  the  fol‐
19       lowing example:
20              FILE *fp = explain_fdopen_or_die(fd, mode);
21
22       fd      The fd, exactly as to be passed to the fdopen(3) system call.
23
24       mode    The mode, exactly as to be passed to the fdopen(3) system call.
25
26       Returns:
27               This  function  only returns on success.  On failure, prints an
28               explanation and exits.
