◆ is_block_inside_fblock()

static int is_block_inside_fblock	(	const SolverBlok *	blok,
		const SolverBlok *	fblok
	)

inlinestatic

Check if a block is included inside another one.

Indicate if a blok is included inside an other block. i.e. indicate if the row range of the first block is included in the one of the second.

Parameters

[in]	blok	The block that is tested for inclusion.
[in]	fblok	The block that is suppose to include the first one.

Return values

true	if the first block is included in the second one.
false	if the first block is not included in the second one.
