Function

GLibSequenceIterCompareFunc

Declaration

gint
(* GSequenceIterCompareFunc) (
  GSequenceIter* a,
  GSequenceIter* b,
  gpointer data
)

Description [src]

A GSequenceIterCompareFunc is a function used to compare iterators. It must return zero if the iterators compare equal, a negative value if a comes before b, and a positive value if b comes before a.

Parameters

`a`	`GSequenceIter`
	A `GSequenceIter`.
	The data is owned by the caller of the function.
`b`	`GSequenceIter`
	A `GSequenceIter`.
	The data is owned by the caller of the function.
`data`	`gpointer`
	User data.

Return value

Returns:	`gint`
	Zero if the iterators are equal, a negative value if `a` comes before `b`, and a positive value if `b` comes before `a`.
