Define Documentation

#define CRC_ALGO_TABLE_DRIVEN   1

The definition of the used algorithm.

This is not used anywhere in the generated code, but it may be used by the application code to call algoritm-specific code, is desired.

Definition at line 33 of file zipcrc.h.

Typedef Documentation

typedef uint_fast32_t zipcrc_t

The type of the CRC values.

This type must be big enough to contain at least 32 bits.

Function Documentation

zipcrc_t zipcrc_update	(	zipcrc_t	crc,
		const void *	data,
		size_t	data_len
	)

Update the crc value with new data.

Parameters:

crc	The current crc value.
data	Pointer to a buffer of data_len bytes.
data_len	Number of bytes in the data buffer.

Returns:

The updated crc value.
