Detailed Description

Macro Definition Documentation

◆ printf_bit

#define printf_bit	(	v,
		w
	)	fprintf_bit( stdout, (v), (w) )

output a bit sequence to the standard output.

Function Documentation

◆ bit_rotate()

ulong bit_rotate	(	ulong	val,
		int	bitwidth,
		int	d
	)

rotate a bit sequence.

bit_rotate() rotates a bit sequence of a value val with the bit width bitwidth. d is a rotation displacement.

Returns: the value converted.

◆ bit_reverse()

ulong bit_reverse	(	ulong	val,
		int	bitwidth
	)

reverse a bit sequence.

bit_reverse() reverses a bit sequence val with the bit width bitwidth.

Returns: the value converted.

◆ sprintf_bit()

void sprintf_bit	(	char *	str,
		ulong	val,
		int	width
	)

convert a bit sequence to a string in binary format.

sprintf_bit() converts a given value val to a string in binary format. The string is stored where a pointer str points. width is the applied bit width. For example, sprintf_bit( str, 0xf, 6 ) makes str "001111".

Note: The size of str has to be more than width + 1 bytes.

See also: fprintf_bit

◆ fprintf_bit()

void fprintf_bit	(	FILE *	fp,
		ulong	val,
		int	width
	)

output a bit sequence to a file in binary format.

fprintf_bit() outputs a given value val to the current position of a file pointed by fp. The output format is the same with that of sprintf_bit().

Note: fprintf_bit() is not available in the kernel space.
