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.

◆ str_to_buf()

int str_to_buf	(	const char *	str,
		void *	_buf,
		unsigned int	buf_bitsize
	)

Parse an unsigned number (provided as a zero-terminated string) into a bit buffer whose size is buf_len bits.

The base of the number is detected between decimal, hexadecimal and octal.

Parameters

str	Input number, zero-terminated string
_buf	Output buffer, allocated by the caller
buf_bitsize	Output buffer size in bits

Returns: Error on invalid or overflowing number

	)

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.
