@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. 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.

@ -146,42 +150,52 @@ The error code indicates the general category of the error. Some error codes,
such as @ref GLFW_NOT_INITIALIZED has only a single meaning, whereas others like
@ref GLFW_PLATFORM_ERROR are used for many different errors.
GLFW usually has much more information about the error than its general category
at the point where it occurred. This is where the error callback comes in.
This callback is called whenever an error occurs. It is set with @ref
glfwSetErrorCallback, a function that may be called regardless of whether GLFW
is initialized.
GLFW often has more information about an error than its general category. You
can retrieve a UTF-8 encoded human-readable description along with the error
code. If no error has occurred since the last call, the description is set to
`NULL`.
@code
const char* description;
int code = glfwGetError(&description);
if (description)
display_error_message(code, description);
@endcode
The retrieved description string is only valid until the next error occurs.
This means you must make a copy of it if you want to keep it.
You can also set an error callback, which will be called each time an error
occurs. It is set with @ref glfwSetErrorCallback.
@code
glfwSetErrorCallback(error_callback);
@endcode
The error callback receives a human-readable description of the error and (when
possible) its cause. The description encoded as UTF-8. The callback is also
provided with an [error code](@ref errors).
The error callback receives the same error code and human-readable description
returned by @ref glfwGetError.
@code
void error_callback(int error, const char* description)
void error_callback(int code, const char* description)
{
puts(description);
display_error_message(code, description);
}
@endcode
The error callback is called after the error code is set, so calling @ref
glfwGetError from within the error callback returns the same value as the
The error callback is called after the error is stored, so calling @ref
glfwGetError from within the error callback returns the same values as the
callback argument.
The description string passed to the callback is only valid until the error
callback returns. This means you must make a copy of it if you want to keep it.
__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
keep the description string.
Do not rely on a currently invalid call to generate a specific error, as in the
future that same call may generate a different error or become valid.
