gtf_range_compare()

static int gtf_range_compare ( const void *  a, const void *  b  )

static

Comparison function for sorting ranges by start, then end.

Parameters

a	pointer to the first range (long[2])
b	pointer to the second range (long[2])

Returns

negative if a < b, 0 if equal, positive if a > b

iter_contigs()

pair_t * iter_contigs	(	pair_t *	ranges,
		size_t *	size
	)

Merges overlapping ranges in a sorted array of pairs.

Parameters

ranges	the array of pairs to merge
size	pointer to the number of pairs in the array, will be updated to the number of merged pairs

Returns

a pointer to the merged array of pairs
