CACE_RANGE_DEF

#define CACE_RANGE_DEF	(		range,
			intvl,
			type
	)

A closed interval of numeric values with optional minimum and maximum.

A single interval struct is defined as intvl_t. A range containing ordered sequence of intervals is defined as range_t

Members of the interval struct are:

• has_min True if this interval has a finite minimum.
• i_min The minimum value of the interval, valid if has_min is true.
• has_max True if this interval has a finite maximum.
• i_max The maximum value of the interval, valid if has_max is true.

Functions for the interval struct are the following:

• intvl_init() Initialize a fully infinite interval.
• intvl_deinit() Clean up state.
• intvl_set_finite() Set the state to a fully finite interval.
• intvl_set_min() Set just the minimum finite extent.
• intvl_set_max() Set just the maximum finite extent.
• intvl_is_infinite() Determine if this interval is open on both ends (is fully infinite).
• intvl_cmp() Compare to intervals by their extents.
• intvl_contains() Determine if a value is within the interval.

Functions for the range struct are the following:

• range_contains() Determine if a value is within the range.
