Functions
int	span_bound_cmp (const SpanBound *b1, const SpanBound *b2)
	Compare two span boundary points, returning <0, 0, or >0 according to whether the first one is less than, equal to, or greater than the second one. More...
int	span_bound_qsort_cmp (const void *a1, const void *a2)
	Comparison function for sorting span bounds. More...
void	span_bounds (const Span *s, double *xmin, double *xmax)
void	span_deserialize (const Span *s, SpanBound *lower, SpanBound *upper)

int	span_lower_cmp (const Span *a, const Span *b)
	Compare the lower bounds of two spans, returning <0, 0, or >0 according to whether the first bound is less than, equal to, or greater than the second one. More...
Span *	span_serialize (SpanBound *lower, SpanBound *upper)
uint8_t *	span_to_wkb_buf (const Span *s, uint8_t *buf, uint8_t variant)

size_t	span_to_wkb_size (const Span *s)
	Return the size in bytes of a span represented in Well-Known Binary (WKB) format. More...
int	span_upper_cmp (const Span *a, const Span *b)
	Compare the upper bounds of two spans, returning <0, 0, or >0 according to whether the first bound is less than, equal to, or greater than the second one. More...
