Detailed Description

This file contains the GM API functions, gm_crc() and gm_crc_str(), which compute 32-bit CRCs on the contents of memory. These functions are not guaranteed to perform any particular variant of the CRC-32, but these functions are useful for creating robust hashing functions.

GM_ENTRY_POINT unsigned long gm_crc (  void *  _ptr, gm_size_t  len )

gm_crc() computes a CRC-32 of the indicated range of memory. Return values: long  Parameters: _ptr  (IN) Pointer to a range of memory. len  (IN) The length of the indicated range of memory. Author: Glenn Brown Version: GM_API_VERSION (as defined in gm.h)

GM_ENTRY_POINT unsigned long gm_crc_str (  const char *  ptr  )

gm_crc_str() computes a CRC-32 for the indicated string. Return values: long  Parameters: ptr  (IN) Pointer to a string. Author: Glenn Brown Version: GM_API_VERSION (as defined in gm.h)
