Synopsis

uint32_t libmem_crc32_direct(const uint8_t *start,
                             size_t size,
                             uint32_t crc);

Description

libmem_crc32_direct computes the CRC-32 checksum of an address range.

start — A pointer to the start of the address range.

size — The size of the address range in bytes.

crc — The initial CRC-32 value.

libmem_crc32_direct returns — The computed CRC-32 value.

This function computes a CRC-32 checksum on a block of data using the standard CRC-32 polynomial (0x04C11DB7). Note that this implementation doesn't reflect the input or the output and the result is not inverted.

Example:

uint32_t crc = 0xFFFFFFFF;

crc = libmem_crc32_direct((uint8_t *)0x10000000, 1024, crc);
