explain_signalfd_or_die(3)				     Library Functions Manual					explain_signalfd_or_die(3)

NAME

       explain_signalfd_or_die - create signalable file descriptor and report errors

SYNOPSIS

       #include <libexplain/signalfd.h>
       int explain_signalfd_or_die(int fildes, const sigset_t *mask, int flags);
       int explain_signalfd_on_error(int fildes, const sigset_t *mask, int flags);

DESCRIPTION

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

       The explain_signalfd_on_error function is used to call the signalfd(2) system call. On failure an explanation will be  printed  to  stderr,
       obtained from the explain_signalfd(3) function, but still returns to the caller.

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

       mask    The mask, exactly as to be passed to the signalfd(2) system call.

       flags   The flags, exactly as to be passed to the signalfd(2) system call.

RETURN VALUE

       The  explain_signalfd_or_die  function only returns on success, see signalfd(2) for more information. On failure, prints an explanation and
       exits, it does not return.

       The explain_signalfd_on_error function always returns the value return by the wrapped signalfd(2) system call.

EXAMPLE

       The explain_signalfd_or_die function is intended to be used in a fashion similar to the following example:
	      int result = explain_signalfd_or_die(fildes, mask, flags);

SEE ALSO

       signalfd(2)
	       create a file descriptor for accepting signals

       explain_signalfd(3)
	       explain signalfd(2) errors

       exit(2) terminate the calling process

NAME

       explain_pread_or_die - seek and read from a file descriptor and report errors

SYNOPSIS

       #include <libexplain/pread.h>
       ssize_t explain_pread_or_die(int fildes, void *data, size_t data_size, off_t offset);
       ssize_t explain_pread_on_error(int fildes, void *data, size_t data_size, off_t offset))

DESCRIPTION

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

       The explain_pread_on_error function is used to call the pread(2) system call. On failure an explanation will be printed to stderr, obtained
       from the explain_pread(3) function, but still returns to the caller.

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

       data    The data, exactly as to be passed to the pread(2) system call.

       data_size
	       The data_size, exactly as to be passed to the pread(2) system call.

       offset  The offset, exactly as to be passed to the pread(2) system call.

RETURN VALUE

       The  explain_pread_or_die function only returns on success, see pread(2) for more information. On failure, prints an explanation and exits,
       it does not return.

       The explain_pread_on_error function always returns the value return by the wrapped pread(2) system call.

EXAMPLE

       The explain_pread_or_die function is intended to be used in a fashion similar to the following example:
	      ssize_t result = explain_pread_or_die(fildes, data, data_size, offset);

SEE ALSO

       pread(2)
	       read from a file descriptor at a given offset

       explain_pread(3)
	       explain pread(2) errors

       exit(2) terminate the calling process
