explain_tcsetattr_or_die(3)				     Library Functions Manual				       explain_tcsetattr_or_die(3)

NAME

       explain_tcsetattr_or_die - set terminal attributes and report errors

SYNOPSIS

       #include <libexplain/tcsetattr.h>
       void explain_tcsetattr_or_die(int fildes, int options, const struct termios *data);
       int explain_tcsetattr_on_error(int fildes, int options, const struct termios *data);

DESCRIPTION

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

       The explain_tcsetattr_on_error function is used to call the tcsetattr(3) system call. On failure an explanation will be printed to  stderr,
       obtained from the explain_tcsetattr(3) function, but still returns to the caller.

       fildes  The fildes, exactly as to be passed to the tcsetattr(3) system call.

       options The options, exactly as to be passed to the tcsetattr(3) system call.

       data    The data, exactly as to be passed to the tcsetattr(3) system call.

RETURN VALUE

       The explain_tcsetattr_or_die function only returns on success, see tcsetattr(3) for more information. On failure, prints an explanation and
       exits, it does not return.

       The explain_tcsetattr_on_error function always returns the value return by the wrapped tcsetattr(3) system call.

EXAMPLE

       The explain_tcsetattr_or_die function is intended to be used in a fashion similar to the following example:
	      explain_tcsetattr_or_die(fildes, options, data);

SEE ALSO

       tcsetattr(3)
	       set terminal attributes

       explain_tcsetattr(3)
	       explain tcsetattr(3) 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
