setPath

public static void setPath(org.lwjgl.system.FunctionProvider sharedLibrary)

Calls setPath(String) with the path of the specified SharedLibrary.

Example usage: GLFWNativeOSMesa.setPath(GL.getFunctionProvider());

Parameters:

sharedLibrary - a FunctionProvider instance that will be cast to SharedLibrary

setPath

public static void setPath(@Nullable
                           java.lang.String path)

Overrides the OSMesa shared library that GLFW loads internally.

This is useful when there's a mismatch between the shared libraries loaded by LWJGL and GLFW.

This method must be called before GLFW initializes OpenGL. The override is available only in the default GLFW build bundled with LWJGL. Using the override with a custom GLFW build will produce a warning in DEBUG mode (but not an error).

Parameters:

path - the OSMesa shared library path, or null to remove the override.
