NAME

       explain_fcntl_or_die - manipulate a file descriptor and report errors

SYNOPSIS

       #include <libexplain/fcntl.h>
       int explain_fcntl_or_die(int fildes, int command, long arg);

DESCRIPTION

       The explain_fcntl_or_die function is used to call the fcntl(2) system call.  On failure an
       explanation will be printed to  stderr,  obtained  from  explain_fcntl(3),  and  then  the
       process terminates by calling exit(EXIT_FAILURE).

       This function is intended to be used in a fashion similar to the following example:
              int result = explain_fcntl_or_die(fildes, command, arg);

       fildes  The fildes, exactly as to be passed to the fcntl(2) system call.

       command The command, exactly as to be passed to the fcntl(2) system call.

       arg     The arg, exactly as to be passed to the fcntl(2) system call.

       Returns:
               This function only returns on success, and it returns whatever was returned by the
               fcntl(2) call; depending on the command, this may have no use.  On failure, prints
               an explanation and exits, it does not return.
