LibCRC API Reference – crc_32()

crc_32( input_str, num_bytes );


Parameter Type Description
input_str const unsigned char * The input byte buffer for which the CRC must be calculated
num_bytes size_t The number of characters in the input buffer

Return Value

Type Description
uint32_t The resulting CRC value


The function crc_32() calculates a 32 bit CRC value of an input byte buffer based on the common 32 bit CRC calculation algorithm. The buffer length is provided as a parameter and the resulting CRC is returned as a return value by the function. The size of the buffer is limited to SIZE_MAX.
