Unigine::CRC32 Class

Header: #include <UnigineChecksum.h>

CRC32 Class

Members


static CRC32Ptr create ( ) #

Default constructor that creates an empty instance.

void begin ( ) #

Initializes a 32-bit CRC checksum with an initial value.

void update ( const void* data, int size ) #

Updates a 32-bit CRC checksum.

Arguments

  • const void* data - Input data pointer.
  • int size - Input data size, in bytes.

int end ( ) #

Finalizes the checksum value by inverting all bits.

int calculate ( const void* data, int size, bool big_endian ) #

Calculates a 32-bit CRC checksum.

Arguments

  • const void* data - Input data pointer.
  • int size - Input data size, in bytes.
  • bool big_endian - Byte ordering flag. Set true to use the big-endian order; false — to use the little-endian order.

Return value

32-bit CRC checksum.

unsigned int calcCrc32 ( const void* data, int size ) #

Calculates a 32-bit CRC checksum.

Arguments

  • const void* data - Input data pointer.
  • int size - Input data size, in bytes.

Return value

32-bit CRC checksum.
