GObjecttype_query

Declaration

void
g_type_query (
  GType type,
  GTypeQuery* query
)

Description

Queries the type system for information about a specific type.

This function will fill in a user-provided structure to hold type-specific information. If an invalid GType is passed in, the type member of the GTypeQuery is 0. All members filled into the GTypeQuery structure should be considered constant and have to be left untouched.

Since GLib 2.78, this function allows queries on dynamic types. Previously it only supported static types.

GType of a static, classed type.

query

Type: GTypeQuery

A user provided structure that is filled in with constant values upon success.

The argument will be set by the function.

The data is owned by the caller of the function.
