Declaration [src]

gboolean
g_match_info_fetch_named_pos(
constGMatchInfo*match_info,
constgchar*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.

Available since: 2.14

TRUE if the position was fetched, FALSE otherwise. If the position cannot be fetched, start_pos and end_pos are left unchanged.
