apply_mask()

bool apply_mask	(		self,
		'bitrange_t'	subrange )

Apply mask to a bitrange 

@param subrange: range *inside* the main bitrange to keep After this operation the main bitrange will be truncated to have only the bits that are specified by subrange. Example: [off=8,nbits=4], subrange[off=1,nbits=2] => [off=9,nbits=2]
@returns success

bitoff()

'uint' bitoff

(

self

)

bitsize()

'uint' bitsize

(

self

)

Get size of the value in bits.

bytesize()

'uint' bytesize

(

self

)

Size of the value in bytes.

compare()

int compare	(		self,
		'bitrange_t'	r )

create_union()

None create_union	(		self,
		'bitrange_t'	r )

Create union of 2 ranges including the hole between them.

empty()

bool empty

(

self

)

Is the bitrange empty?

extract()

bool extract	(		self,
		'void const *'	src,

has_common()

bool has_common	(		self,
