Function Documentation

bytes_be_to_uint()

unsigned bytes_be_to_uint

(

const unsigned char *

bytes

)

Packs 4 big endian bytes into an unsigned.

Parameters

bytes

Pointer to an array of bytes that will be packed.

Returns

The packed unsigned.

Remarks

Assumes the passed array is least 4 bytes in size.

Assumes unsigned is 4 bytes in size.

swap_endian()

void swap_endian	(	void *	data,
		unsigned	elem_size,
		unsigned	num )

Swaps the endianness of data. Each element is swapped individually by reversing its bytes.

Parameters

data	Pointer to data to be swapped.
elem_size	Size in bytes of each element.
num	Number of elements.

Remarks

The caller must ensure that the data is at least elem_size * num bytes in size.

uint_to_bytes_be()

void uint_to_bytes_be	(	unsigned char *	bytes,
		unsigned	value )

Packs an unsigned into 4 big endian bytes.

Parameters

bytes	Pointer to an array where the bytes will be stored.
value	The values that will be packed into the array.

Remarks

Assumes the passed array is least 4 bytes in size.

Assumes unsigned is 4 bytes in size.
