Functions
Description
GITypeInfo represents a type. You can retrieve a type info from an argument (see GIArgInfo), a functions return value (see GIFunctionInfo), a field (see GIFieldInfo), a property (see GIPropertyInfo), a constant (see GIConstantInfo) or for a union discriminator (see GIUnionInfo).
A type can either be a of a basic type which is a standard C primitive
type or an interface type. For interface types you need to call
g_type_info_get_interface() to get a reference to the base info for that
interface.
Functions
g_type_info_is_pointer ()
gboolean
g_type_info_is_pointer (GITypeInfo *info);
Obtain if the type is passed as a reference.
Note that the types of GI_DIRECTION_OUT and GI_DIRECTION_INOUT parameters
will only be pointers if the underlying type being transferred is a pointer
(i.e. only if the type of the C function’s formal parameter is a pointer to a
pointer).
g_type_info_get_tag ()
GITypeTag
g_type_info_get_tag (GITypeInfo *info);
Obtain the type tag for the type. See GITypeTag for a list of type tags.
g_type_info_get_param_type ()
GITypeInfo * g_type_info_get_param_type (GITypeInfo *info,gint n);
Obtain the parameter type n
.
g_type_info_get_interface ()
GIBaseInfo *
g_type_info_get_interface (GITypeInfo *info);
For types which have GI_TYPE_TAG_INTERFACE such as GObjects and boxed values,
this function returns full information about the referenced type. You can then
inspect the type of the returned GIBaseInfo to further query whether it is
a concrete GObject, a GInterface, a structure, etc. using g_base_info_get_type().
g_type_info_get_array_length ()
gint
g_type_info_get_array_length (GITypeInfo *info);
Obtain the array length of the type. The type tag must be a GI_TYPE_TAG_ARRAY or -1 will returned.
g_type_info_get_array_fixed_size ()
gint
g_type_info_get_array_fixed_size (GITypeInfo *info);
Obtain the fixed array size of the type. The type tag must be a GI_TYPE_TAG_ARRAY or -1 will returned.
g_type_info_is_zero_terminated ()
gboolean
g_type_info_is_zero_terminated (GITypeInfo *info);
Obtain if the last element of the array is NULL. The type tag must be a
GI_TYPE_TAG_ARRAY or FALSE will returned.
g_type_info_get_array_type ()
GIArrayType
g_type_info_get_array_type (GITypeInfo *info);
Obtain the array type for this type. See GIArrayType for a list of possible values. If the type tag of this type is not array, -1 will be returned.
