glfwGetCursorPos function

void glfwGetCursorPos(Pointer<GLFWwindow> window, Pointer<Double> xpos, Pointer<Double> ypos)

! @brief Retrieves the position of the cursor relative to the content area of the window.

This function returns the position of the cursor, in screen coordinates, relative to the upper-left corner of the content area of the specified window.

If the cursor is disabled (with GLFW_CURSOR_DISABLED) then the cursor position is unbounded and limited only by the minimum and maximum values of a double.

The coordinate can be converted to their integer equivalents with the floor function. Casting directly to an integer type works for positive coordinates, but fails for negative ones.

Any or all of the position arguments may be NULL. If an error occurs, all non-NULL position arguments will be set to zero.

@paramin window The desired window. @paramout xpos Where to store the cursor x-coordinate, relative to the left edge of the content area, or NULL. @paramout ypos Where to store the cursor y-coordinate, relative to the to top edge of the content area, or NULL.

@errors Possible errors include @ref GLFW_NOT_INITIALIZED and @ref GLFW_PLATFORM_ERROR.

@thread_safety This function must only be called from the main thread.

@since Added in version 3.0. Replaces glfwGetMousePos.
