//
// Dynamic loader for unicorn shared library in windows and linux.
// This was made for v0.9 of unicorn.
// Newer versions of unicorn may require changes to these files.
//
// Windows Notes:
// If an absolute path to unicorn.dll is passed into uc_dyn_load() it will
// still try to load the rest of the dependent dlls (ie libglib-2.0-0.dll etc)
// from standard dll paths. This is usually the directory that the main
// exe file, that loaded unicorn.dll, is in. This is standard behaviour for
// Windows dll files, and not specific to unicorn dlls.
//
// So putting all dlls in their own directory and then attempting to load
// unicorn.dll from that directory via an absolute path will cause
// uc_dyn_load() to fail.
//
// The easiest way around this is to place all dlls in the same directory
// as your main exe file. Other ways around this are using various flags
// for LoadLibraryEx() or by calling SetDllDirectory().
//
// LoadLibraryEx info:

// SetDllDirectory() info:
