PangoOT.Info.find_feature

### Method

# PangoOT Infofind_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.

#### Parameters

`table_type` | `PangoOTTableType`
| The table type to obtain information about.
`feature_tag` | `PangoOTTag`
| The tag of the feature to find.
`script_index` | `guint`
| The index of the script.
`language_index` | `guint`
| The index of the language whose features are searched, or `PANGO_OT_DEFAULT_LANGUAGE` to use the default language of the script.
`feature_index` | `guint*`
| Location to store the index of the feature.
| The argument will be set by the function.
| The argument can be `NULL`.
| The instance takes ownership of the data, and is responsible for freeing it.

#### Return value

Returns: | `gboolean`
| `TRUE` if the feature was found.
