Method

PangoOTInfofind_feature

Declaration [src]

gboolean
pango_ot_info_find_feature (
  PangoOTInfo* info,
  PangoOTTableType table_type,
  PangoOTTag feature_tag,
  guint script_index,
  guint language_index,
  guint* feature_index
)

Description [src]

Finds the index of a feature.

If the feature is not found, sets feature_index to PANGO_OT_NO_FEATURE, which is safe to pass to pango_ot_ruleset_add_feature() and similar functions.

In the future, this may set feature_index to an special value that if used in pango_ot_ruleset_add_feature() will ask Pango to synthesize the requested feature based on Unicode properties and data. However, this function will still return FALSE in those cases. So, users may want to ignore the return value of this function in certain cases.

Type: PangoOTTableType

The table type to obtain information about.

feature_tag

script_index

language_index

The index of the language whose features are searched, or PANGO_OT_DEFAULT_LANGUAGE to use the default language of the script.

Type: guint*

Location to store the index of the feature.

The argument will be set by the function.

The argument can be NULL.

Return value
