int hex2bin	(	u8 *	dst,
		const char *	src,
		size_t	count
	)

hex2bin - convert an ascii hexadecimal string to its binary representation : binary result : ascii hexadecimal string : result length

Return 0 on success, -1 in case of bad input.

void hex_dump_to_buffer	(	const void *	buf,
		size_t	len,
		int	rowsize,
		int	groupsize,
		char *	linebuf,
		size_t	linebuflen,
		bool	ascii
	)

hex_dump_to_buffer - convert a blob of data to "hex ASCII" in memory : data blob to dump : number of bytes in the : number of bytes to print per line; must be 16 or 32 : number of bytes to print at a time (1, 2, 4, 8; default = 1) : where to put the converted data : total size of , including space for terminating NUL : include ASCII after the hex output

hex_dump_to_buffer() works on one "line" of output at a time, i.e., 16 or 32 bytes of input data converted to hex + ASCII output.

Given a buffer of u8 data, hex_dump_to_buffer() converts the input data to a hex + ASCII dump at the supplied memory location. The converted output is always NUL-terminated.

E.g.: hex_dump_to_buffer(frame->data, frame->len, 16, 1, linebuf, sizeof(linebuf), true);

example output buffer: 40 41 42 43 44 45 46 47 48 49 4a 4b 4c 4d 4e 4f

int hex_to_bin

(

char

ch

)

hex_to_bin - convert a hex digit to its real value : ascii character represents hex digit

hex_to_bin() converts one hex digit to its actual value or -1 in case of bad input.
