Documentation

data SDLException Source #

Error details about a failure to call an SDL routine. Almost all functions in this library have the ability to produce exceptions of this type. Inspection should help you learn more about what has gone wrong.

Constructors

SDLCallFailed	A call to a low-level SDL C function failed unexpectedly.
Fields sdlExceptionCaller :: !Text The Haskell routine that was trying to call a C function sdlFunction :: !Text The C function that was called and produced an error sdlExceptionError :: !Text SDL's understanding of what has gone wrong
SDLUnexpectedArgument	An SDL C function was called with an unexpected argument.
Fields sdlExceptionCaller :: !Text The Haskell routine that was trying to call a C function sdlFunction :: !Text The C function that was called and produced an error sdlUnknownValue :: !String The argument that SDL failed to understand
SDLUnknownHintValue	A hint was attempted to be set, but SDL does not know about this hint.
Fields sdlHint :: !String The hint that could not be set sdlUnknownValue :: !String The argument that SDL failed to understand
