Detailed Description

Handles the opening and closing of DLLs.

This class can be used to open a DLL and get some function pointers from it. Since the DLL is freed when this object is deleted, it's handy for managing library lifetimes using RAII.

Constructor & Destructor Documentation

DynamicLibrary::DynamicLibrary ( )

noexcept

Creates an unopened DynamicLibrary object.

Call open() to actually open one.

DynamicLibrary::DynamicLibrary

(

const String &

name

)

DynamicLibrary::~DynamicLibrary

(

)

Destructor.

If a library is currently open, it will be closed when this object is destroyed.

Member Function Documentation

bool DynamicLibrary::open

(

const String &

name

)

Opens a DLL.

The name and the method by which it gets found is of course platform-specific, and may or may not include a path, depending on the OS. If a library is already open when this method is called, it will first close the library before attempting to load the new one.

Returns

true if the library was successfully found and opened.

void DynamicLibrary::close

(

)

Releases the currently-open DLL, or has no effect if none was open.

void* DynamicLibrary::getFunction ( const String &  functionName )

noexcept

Tries to find a named function in the currently-open DLL, and returns a pointer to it.

If no library is open, or if the function isn't found, this will return a null pointer.

void* DynamicLibrary::getNativeHandle ( ) const

noexcept

Returns the platform-specific native library handle.

You'll need to cast this to whatever is appropriate for the OS that's in use.
