Detailed Description

FunctionDecl - An instance of this class is created to represent a function declaration or definition.

Since a given function can be declared several times in a program, there may be several FunctionDecls that correspond to that function. Only one of those FunctionDecls will be found when traversing the list of declarations in the context of the FunctionDecl (e.g., the translation unit); this FunctionDecl contains all of the information known about the function. Other, previous declarations of the function are available via the getPreviousDecl() chain.

Returns a value indicating whether this function corresponds to a builtin function.

The function corresponds to a built-in function if it is declared at translation scope or within an extern "C" block and its name matches with the name of a builtin.

FunctionDecl * FunctionDecl::getInstantiatedFromMemberFunction ( ) const

If this function is an instantiation of a member function of a class template specialization, retrieves the function from which it was instantiated.

This routine will return non-NULL for (non-templated) member functions of class templates and for instantiations of function templates. For example, given:

 template<typename T>
 struct X {
   void f(T);
 };

The declaration for X<int>::f is a (non-templated) FunctionDecl whose parent is the class template specialization X<int>. For this declaration, getInstantiatedFromFunction() will return the FunctionDecl X<T>::A. When a complete definition of X<int>::A is required, it will be instantiated from the declaration returned by getInstantiatedFromMemberFunction().

bool clang::FunctionDecl::isDeleted ( ) const [inline]

Whether this function has been deleted.

A function that is "deleted" (via the C++0x "= delete" syntax) acts like a normal function, except that it cannot actually be called or have its address taken. Deleted functions are typically used in C++ overload resolution to attract arguments whose type or lvalue/rvalue-ness would permit the use of a different overload that would behave incorrectly. For example, one might use deleted functions to ban implicit conversion from a floating-point number to an Integer type:

 struct Integer {
   Integer(long); // construct from a long
   Integer(double) = delete; // no construction from float or double
   Integer(long double) = delete; // no construction from long double
 };

bool FunctionDecl::isInlineDefinitionExternallyVisible ( ) const

For an inline function definition in C or C++, determine whether the definition will be externally visible.

Inline function definitions are always available for inlining optimizations. However, depending on the language dialect, declaration specifiers, and attributes, the definition of an inline function may or may not be "externally" visible to other translation units in the program.

In C99, inline definitions are not externally visible by default. However, if even one of the global-scope declarations is marked "extern inline", the inline definition becomes externally visible (C99 6.7.4p6).

In GNU89 mode, or if the gnu_inline attribute is attached to the function definition, we use the GNU semantics for inline, which are nearly the opposite of C99 semantics. In particular, "inline" by itself will create an externally visible symbol, but "extern inline" will not create an externally visible symbol.
