glfwGetProcAddress function

GLFWglproc glfwGetProcAddress(String procname)

! @brief Returns the address of the specified function for the current context.

This function returns the address of the specified OpenGL or OpenGL ES core or extension function(@ref context_glext), if it is supported by the current context.

A context must be current on the calling thread. Calling this function without a current context will cause a @ref GLFW_NO_CURRENT_CONTEXT error.

This function does not apply to Vulkan. If you are rendering with Vulkan, see @ref glfwGetInstanceProcAddress, vkGetInstanceProcAddr and vkGetDeviceProcAddr instead.

@paramin procname The ASCII encoded name of the function. @return The address of the function, or NULL if an error(@ref error_handling) occurred.

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

@remark The address of a given function is not guaranteed to be the same between contexts.

@remark This function may return a non-NULL address despite the associated version or extension not being available. Always check the context version or extension string first.

@pointer_lifetime The returned function pointer is valid until the context is destroyed or the library is terminated.

@thread_safety This function may be called from any thread.
