ParseErrorFunc

type C_ParseErrorFunc = Ptr ParseLocation -> Ptr ParseLocation -> Ptr GError -> Ptr () -> IO ()

Type for the callback on the (unwrapped) C side.

type ParseErrorFunc

Arguments

 = ParseLocation

start: start of the error location

-> ParseLocation

end: end of the error location

-> GError

error: the error

-> IO ()

Type of callback that is called when an error occurs during node deserialization.

type ParseErrorFunc_WithClosures

Arguments

 = ParseLocation

start: start of the error location

-> ParseLocation

end: end of the error location

-> GError

error: the error

-> Ptr ()

userData: user data

-> IO ()

Type of callback that is called when an error occurs during node deserialization.

drop_closures_ParseErrorFunc :: ParseErrorFunc -> ParseErrorFunc_WithClosures

A simple wrapper that ignores the closure arguments.

dynamic_ParseErrorFunc

Arguments

:: (HasCallStack, MonadIO m)

=> FunPtr C_ParseErrorFunc

-> ParseLocation

start: start of the error location

-> ParseLocation

end: end of the error location

-> GError

error: the error

-> Ptr ()

userData: user data

-> m ()

Given a pointer to a foreign C function, wrap it into a function callable from Haskell.

genClosure_ParseErrorFunc :: MonadIO m => ParseErrorFunc -> m (GClosure C_ParseErrorFunc)

Wrap the callback into a GClosure.

mk_ParseErrorFunc :: C_ParseErrorFunc -> IO (FunPtr C_ParseErrorFunc)

Generate a function pointer callable from C code, from a C_ParseErrorFunc.

noParseErrorFunc :: Maybe ParseErrorFunc

A convenience synonym for Nothing :: Maybe ParseErrorFunc.

noParseErrorFunc_WithClosures :: Maybe ParseErrorFunc_WithClosures

A convenience synonym for Nothing :: Maybe ParseErrorFunc_WithClosures.

wrap_ParseErrorFunc :: Maybe (Ptr (FunPtr C_ParseErrorFunc)) -> ParseErrorFunc_WithClosures -> C_ParseErrorFunc

Wrap a ParseErrorFunc into a C_ParseErrorFunc.
