Detailed Description
Represents 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.

Retrieve the body (definition) of the function.
The function body might be in any of the (re-)declarations of this function. The variant that accepts a FunctionDecl pointer will set that function declaration to the actual declaration containing the body (if there is one). NOTE: For checking if there is a body, use hasBody() instead, to avoid unnecessary AST de-serialization of the body.

◆ getBuiltinID()
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. The returned value will be 0 for functions that do not correspond to a builtin, a value of type Builtin::ID if in the target-independent range [1,Builtin::First), or a target-specific builtin value.

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

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:

◆ isInlineDefinitionExternallyVisible()
| bool FunctionDecl::isInlineDefinitionExternallyVisible | ( | ) | const |
For an inline function definition in C, or for a gnu_inline function in 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.

Determines whether this function is one of the replaceable global allocation functions: void *operator new(size_t); void *operator new(size_t, const std::nothrow_t &) noexcept; void *operator new[](size_t); void *operator new[](size_t, const std::nothrow_t &) noexcept; void operator delete(void *) noexcept; void operator delete(void *, std::size_t) noexcept; [C++1y] void operator delete(void *, const std::nothrow_t &) noexcept; void operator delete[](void *) noexcept; void operator delete[](void *, std::size_t) noexcept; [C++1y] void operator delete[](void *, const std::nothrow_t &) noexcept; These functions have special behavior under C++1y [expr.new]: An implementation is allowed to omit a call to a replaceable global allocation function.
[...]
If this function is an aligned allocation/deallocation function, return the parameter number of the requested alignment through AlignmentParam.
If this function is an allocation/deallocation function that takes the std::nothrow_t tag, return true through IsNothrow,
