// .NAME vtkDynamicLoader - class interface to system dynamic libraries
// .SECTION Description
// vtkDynamicLoader provides a portable interface to loading dynamic
// libraries into a process.
// .SECTION See Also
// A more portable and lightweight solution is kwsys::DynamicLoader

// Description:
// Load a dynamic library into the current process.
// The returned vtkLibHandle can be used to access the symbols in the
// library.
static vtkLibHandle OpenLibrary(const char*);
// Description:
// Attempt to detach a dynamic library from the
