Unigine::Checksum Class

Checksum Class

Members

int CRC32 ( const void * data, int size, bool big_endian ) #

Arguments

• const void * data - Input data pointer.
• int size - Input data size, in bytes.
• bool big_endian - Byte ordering flag. true if a big-endian order is used; false a little-endian order is used.

Return value

Arguments

• unsigned int * value - 128-bit MD5 checksum (array of 4 unsigned int elements).
• const void * data - Input data pointer.
• int size - Input data size, in bytes.
• bool big_endian - Byte ordering flag. true if a big-endian order is used; false a little-endian order is used.
