pure nothrow @safe char[] demangle(return scope const(char)[] buf, return scope char[] dst = null, CXX_DEMANGLER __cxa_demangle = null);

Demangles D/C++ mangled names. If it is not a D/C++ mangled name, it returns its argument name.

Parameters:

const(char)[] `buf`	The string to demangle.
char[] `dst`	An optional destination buffer.
CXX_DEMANGLER `__cxa_demangle`	optional C++ demangler

Returns:

The demangled name or the original string if the name is not a mangled D/C++ name.

pure nothrow @safe char[] demangleType(const(char)[] buf, char[] dst = null);

Demangles a D mangled type.

Parameters:

const(char)[] `buf`	The string to demangle.
char[] `dst`	An optional destination buffer.

Returns:

The demangled type name or the original string if the name is not a mangled D type.

pure nothrow @safe char[] reencodeMangled(return scope const(char)[] mangled);

reencode a mangled symbol name that might include duplicate occurrences of the same identifier by replacing all but the first occurence with a back reference.

Parameters:

const(char)[] mangled The mangled string representing the type

Returns:

The mangled name with deduplicated identifiers

pure nothrow @safe char[] mangle(T)(return scope const(char)[] fqn, return scope char[] dst = null);

Mangles a D symbol.

Parameters:

T	The type of the symbol.
const(char)[] `fqn`	The fully qualified name of the symbol.
char[] `dst`	An optional destination buffer.

Returns:

The mangled name for a symbols of type T and the given fully qualified name.

Examples:

assert(mangle!int("a.b") == "_D1a1bi");
assert(mangle!(char[])("test.foo") == "_D4test3fooAa");
assert(mangle!(int function(int))("a.b") == "_D1a1bPFiZi");

pure nothrow @safe char[] mangleFunc(T : FT*, FT)(return scope const(char)[] fqn, return scope char[] dst = null) if (is(FT == function));

Mangles a D function.

Parameters:

T	function pointer type.
const(char)[] `fqn`	The fully qualified name of the symbol.
char[] `dst`	An optional destination buffer.

Returns:

The mangled name for a function with function pointer type T and the given fully qualified name.

enum string cPrefix;

C name mangling is done by adding a prefix on some platforms.

nothrow @trusted CXX_DEMANGLER getCXXDemangler();

Returns:

a CXX_DEMANGLER if a C++ stdlib is loaded
