@section error_handling Error handling
Some GLFW functions have return values that indicate an error, but this is often
not very helpful when trying to figure out _why_ the error occurred. Some
functions also return otherwise valid values on error. Finally, far from all
GLFW functions have return values.
not very helpful when trying to figure out _why_ the error occurred. Other
functions have no return value reserved for errors, so error notification needs
a separate channel. Finally, far from all GLFW functions have return values.

error occurs. It is set with @ref glfwSetErrorCallback, a function that may be

such as @ref GLFW_NOT_INITIALIZED has only a single meaning, whereas others like
@ref GLFW_PLATFORM_ERROR are used for many different errors.
Reported errors are never fatal. As long as GLFW was successfully initialized,
it will remain initialized and in a safe state until terminated regardless of
how many errors occur. If an error occurs during initialization that causes
@ref glfwInit to fail, any part of the library that was initialized will be
safely terminated.
The description string is only valid until the error callback returns, as it may
have been generated specifically for that error. This lets GLFW provide much
more specific error descriptions but means you must make a copy if you want to
