## Functions

### GI_TYPE_TAG_IS_BASIC()

    #define GI_TYPE_TAG_IS_BASIC(tag) ((tag) < GI_TYPE_TAG_ARRAY || (tag) == GI_TYPE_TAG_UNICHAR)

Checks if `tag` is a basic type.

#### Parameters

tag | a type tag |

Since: 1.72

### GI_TYPE_TAG_IS_CONTAINER()

    #define             GI_TYPE_TAG_IS_CONTAINER(tag)

Checks if `tag` is a container type. That is, a type which may have a nonnull return from `g_type_info_get_param_type()`.

#### Parameters

tag | a type tag |

Since: 1.72

### GI_TYPE_TAG_IS_NUMERIC()

    #define GI_TYPE_TAG_IS_NUMERIC(tag) ((tag) >= GI_TYPE_TAG_INT8 && (tag) <= GI_TYPE_TAG_DOUBLE)

Checks if `tag` is a numeric type. That is, integer or floating point.

#### Parameters

tag | a type tag |

Since: 1.72

### G_TYPE_TAG_IS_BASIC()

    #define G_TYPE_TAG_IS_BASIC(tag) GI_TYPE_TAG_IS_BASIC(tag)

`G_TYPE_TAG_IS_BASIC` has been deprecated since version 1.72 and should not be used in newly-written code.

Use `GI_TYPE_TAG_IS_BASIC()` instead

Checks if `tag` is a basic type.

#### Parameters

tag | a type tag |

### g_type_tag_to_string ()

    const gchar *
    g_type_tag_to_string (GITypeTag type);

Obtain a string representation of `type`

#### Parameters

type | the type_tag |

#### Returns

the string
