- * lib/misc/lib_crc32.c
- *
- * This file is a part of NuttX:
- *
- *   Copyright (C) 2010-2011 Gregory Nutt. All rights reserved.
- *
- * The logic in this file was developed by Gary S. Brown:
- *
- *   COPYRIGHT (C) 1986 Gary S. Brown.  You may use this program, or code or tables
- *   extracted from it, as desired without restriction.
- *
- * First, the polynomial itself and its table of feedback terms.  The polynomial is:
- *
- *    X^32+X^26+X^23+X^22+X^16+X^12+X^11+X^10+X^8+X^7+X^5+X^4+X^2+X^1+X^0
- *
- * Note that we take it "backwards" and put the highest-order term in the lowest-order bit.
- * The X^32 term is "implied"; the LSB is the X^31 term, etc.  The X^0 term (usually shown
- * as "+1") results in the MSB being 1
- *
- * Note that the usual hardware shift register implementation, which is what we're using
- * (we're merely optimizing it by doing eight-bit chunks at a time) shifts bits into the
- * lowest-order term.  In our implementation, that means shifting towards the right.  Why
- * do we do it this way?  Because the calculated CRC must be transmitted in order from
- * highest-order term to lowest-order term.  UARTs transmit characters in order from LSB
- * to MSB.  By storing the CRC this way we hand it to the UART in the order low-byte to
- * high-byte; the UART sends each low-bit to hight-bit; and the result is transmission bit
- * by bit from highest- to lowest-order term without requiring any bit shuffling on our
- * part.  Reception works similarly
- *
- * The feedback terms table consists of 256, 32-bit entries.  Notes
- *
- * - The table can be generated at runtime if desired; code to do so is shown later.  It
- *   might not be obvious, but the feedback terms simply represent the results of eight
- *   shift/xor operations for all combinations of data and CRC register values
- *
- * - The values must be right-shifted by eight bits by the updcrc logic; the shift must
- *   be u_(bring in zeroes).  On some hardware you could probably optimize the shift in
- *   assembler by using byte-swap instructions polynomial $edb88320

- * Name: sendfile
- *
- * Description:
- *   sendfile() copies data between one file descriptor and another.
- *   sendfile() basically just wraps a sequence of reads() and writes()
- *   to perform a copy.  It serves a purpose in systems where there is
- *   a penalty for copies to between user and kernal space, but really
- *   nothing in NuttX but provide some Linux compatible (and adding
- *   another 'almost standard' interface). 
- *
- *   NOTE: This interface is *not* specified in POSIX.1-2001, or other
- *   standards.  The implementation here is very similar to the Linux
- *   sendfile interface.  Other UNIX systems implement sendfile() with
- *   different semantics and prototypes.  sendfile() should not be used
- *   in portable programs.
- *
- * Input Parmeters:
- *   infd   - A file (or socket) descriptor opened for reading
- *   outfd  - A descriptor opened for writing.
- *   offset - If 'offset' is not NULL, then it points to a variable
- *            holding the file offset from which sendfile() will start
- *            reading data from 'infd'.  When sendfile() returns, this
- *            variable will be set to the offset of the byte following
- *            the last byte that was read.  If 'offset' is not NULL,
- *            then sendfile() does not modify the current file offset of
- *            'infd'; otherwise the current file offset is adjusted to
- *            reflect the number of bytes read from 'infd.'
- *
- *            If 'offset' is NULL, then data will be read from 'infd'
- *            starting at the current file offset, and the file offset
- *            will be updated by the call.
- *   count -  The number of bytes to copy between the file descriptors.
- *
- * Returned Value:
- *   If the transfer was successful, the number of bytes written to outfd is
- *   returned.  On error, -1 is returned, and errno is set appropriately.
- *   There error values are those returned by read() or write() plus:
- *
- *   EINVAL - Bad input parameters.
- *   ENOMEM - Could not allocated an I/O buffer
- *
