/** \class DynamicLoader
|
|
* \brief Portable loading of dynamic libraries or dll's.
|
|
*
|
|
* DynamicLoader provides a portable interface to loading dynamic
|
|
* libraries or dll's into a process.
|
|
*
|
|
* Directory currently works with Windows, Apple, HP-UX and Unix (POSIX)
|
|
* operating systems
|
|
*
|
|
* \warning dlopen on *nix system works the following way:
|
|
* If filename contains a slash ("/"), then it is interpreted as a (relative
|
|
* or absolute) pathname. Otherwise, the dynamic linker searches for the
|
|
* library as follows : see ld.so(8) for further details):
|
|
* Whereas this distinction does not exist on Win32. Therefore ideally you
|
|
* should be doing full path to garantee to have a consistent way of dealing
|
|
* with dynamic loading of shared library.
|
|
*
|
|
* \warning the Cygwin implementation do not use the Win32 HMODULE. Put extra
|
|
* condition so that we can include the correct declaration (POSIX)
