A reference to a type declaration.

A type reference occurs anywhere where a type is named but not declared. For example, given:

The typedef is a declaration of size_type (CXCursor_TypedefDecl), while the type of the variable "size" is referenced. The cursor referenced by the type of size is the typedef for size_type.

A reference to a class template, function template, template template parameter, or class template partial specialization.

A reference to a namespace or namespace alias.

A reference to a member of a struct, union, or class that occurs in some non-expression context, e.g., a designated initializer.

This cursor kind is used to describe the jump to "start_over" in the goto statement in the following example:

A label reference cursor refers to a label statement.

A reference to a set of overloaded functions or function templates that has not yet been resolved to a specific function or function template.

An overloaded declaration reference cursor occurs in C++ templates where a dependent name refers to a function. For example:

Here, the identifier "swap" is associated with an overloaded declaration reference. In the template definition, "swap" refers to either of the two "swap" functions declared above, so both results will be available. At instantiation time, "swap" may also refer to other functions found via argument-dependent lookup (e.g., the "swap" function at the end of the example).

The functions clang_getNumOverloadedDecls() and clang_getOverloadedDecl() can be used to retrieve the definitions referenced by this cursor.
