_buffer	The buffer whose bits will be set. Do not use uninitialized buffer or clang static analyzer emits a warning.
first	The bit offset in `_buffer` to start writing (0-63).
num	The number of bits from `value` to copy (1-64).
value	Up to 64 bits that will be copied to _buffer.

◆ flip_u32()

uint32_t flip_u32	(	uint32_t	value,
		unsigned	width
	)

Inverts the ordering of bits inside a 32-bit word (e.g.

31..0 -> 0..31). This routine can be used to flip smaller data types by using smaller values for width.

Parameters

value	The word to flip.
width	The number of bits in value (2-32).

Returns: A 32-bit word with value in reversed bit-order.

◆ hexify()

size_t hexify	(	char *	hex,
		const uint8_t *	bin,
		size_t	count,
		size_t	length
	)

Convert binary data into a string of hexadecimal pairs.

Parameters

[out]	hex	Buffer to store string of hexadecimal pairs. The buffer size must be at least `length`.
[in]	bin	Buffer with binary data to convert into hexadecimal pairs.
[in]	count	Number of bytes to convert.
[in]	length	Maximum number of characters, including null-terminator, to store into `hex`.

Returns: The length of the converted string excluding null-terminator.

◆ unhexify()

size_t unhexify	(	uint8_t *	bin,
		const char *	hex,
		size_t	count
	)

Convert a string of hexadecimal pairs into its binary representation.

Parameters

[out]	bin	Buffer to store binary representation. The buffer size must be at least `count`.
[in]	hex	String with hexadecimal pairs to convert into its binary representation.
[in]	count	Number of hexadecimal pairs to convert.

Returns: The number of converted hexadecimal pairs.
