Macro Definition Documentation

CRC32_POLY_LE

#define CRC32_POLY_LE   0xedb88320

CRC32 polynomial commonly used for little endian CRC32.

Definition at line 21 of file crc32.h.

Function Documentation

crc32_le()

uint32_t crc32_le	(	uint32_t	poly,
		uint32_t	seed,
		const void *	data,
		size_t	data_len
	)

Calculate the CRC32 value of the given data.

Parameters

poly	The polynomial of the CRC
seed	The seed to use (mostly either 0 or 0xffffffff)
data	The data to calculate the CRC32 of
data_len	The length of the data in data in bytes

Returns

The CRC value of the first data_len bytes at data

Note

This function can be used to incrementally compute the CRC one chunk of data at a time by using the CRC32 of the previous chunk as seed for the next chunk.
