Declaration [src]
gboolean
g_match_info_fetch_named_pos (
const GMatchInfo* match_info,
const gchar* name,
gint* start_pos,
gint* end_pos
)
Description [src]
Retrieves the position in bytes of the capturing parentheses named name.
If name is a valid sub pattern name but it didn’t match anything
(e.g. sub pattern "X", matching "b" against "(?P<X>a)?b")
then start_pos and end_pos are set to -1 and TRUE is returned.
As end_pos is set to the byte after the final byte of the match (on success),
the length of the match can be calculated as end_pos - start_pos.
