-- t'GI.Gio.Interfaces.Converter.Converter' is implemented by objects that convert

-- | This is the main operation used when converting data. It is to be called
-- multiple times in a loop, and each time it will do some work, i.e.
-- producing some output (in /@outbuf@/) or consuming some input (from /@inbuf@/) or
-- both. If its not possible to do any work an error is returned.
-- 
-- Note that a single call may not consume all input (or any input at all).
-- Also a call may produce output even if given no input, due to state stored
-- in the converter producing output.
-- 
-- If any data was either produced or consumed, and then an error happens, then
-- only the successful conversion is reported and the error is returned on the
-- next call.
-- 
-- A full conversion loop involves calling this method repeatedly, each time
-- giving it new input and space output space. When there is no more input
-- data after the data in /@inbuf@/, the flag 'GI.Gio.Flags.ConverterFlagsInputAtEnd' must be set.
-- The loop will be (unless some error happens) returning 'GI.Gio.Enums.ConverterResultConverted'
-- each time until all data is consumed and all output is produced, then
-- 'GI.Gio.Enums.ConverterResultFinished' is returned instead. Note, that 'GI.Gio.Enums.ConverterResultFinished'
-- may be returned even if 'GI.Gio.Flags.ConverterFlagsInputAtEnd' is not set, for instance
-- in a decompression converter where the end of data is detectable from the
-- data (and there might even be other data after the end of the compressed data).
-- 
-- When some data has successfully been converted /@bytesRead@/ and is set to
-- the number of bytes read from /@inbuf@/, and /@bytesWritten@/ is set to indicate
-- how many bytes was written to /@outbuf@/. If there are more data to output
-- or consume (i.e. unless the 'GI.Gio.Flags.ConverterFlagsInputAtEnd' is specified) then
-- 'GI.Gio.Enums.ConverterResultConverted' is returned, and if no more data is to be output
-- then 'GI.Gio.Enums.ConverterResultFinished' is returned.
-- 
-- On error 'GI.Gio.Enums.ConverterResultError' is returned and /@error@/ is set accordingly.
-- Some errors need special handling:
-- 
-- 'GI.Gio.Enums.IOErrorEnumNoSpace' is returned if there is not enough space
-- to write the resulting converted data, the application should
-- call the function again with a larger /@outbuf@/ to continue.
-- 
-- 'GI.Gio.Enums.IOErrorEnumPartialInput' is returned if there is not enough
-- input to fully determine what the conversion should produce,
-- and the 'GI.Gio.Flags.ConverterFlagsInputAtEnd' flag is not set. This happens for
-- example with an incomplete multibyte sequence when converting text,
-- or when a regexp matches up to the end of the input (and may match
-- further input). It may also happen when /@inbufSize@/ is zero and
-- there is no more data to produce.
-- 
-- When this happens the application should read more input and then
-- call the function again. If further input shows that there is no
-- more data call the function again with the same data but with
-- the 'GI.Gio.Flags.ConverterFlagsInputAtEnd' flag set. This may cause the conversion
-- to finish as e.g. in the regexp match case (or, to fail again with
-- 'GI.Gio.Enums.IOErrorEnumPartialInput' in e.g. a charset conversion where the
-- input is actually partial).
-- 
-- After 'GI.Gio.Interfaces.Converter.converterConvert' has returned 'GI.Gio.Enums.ConverterResultFinished' the
-- converter object is in an invalid state where its not allowed
-- to call 'GI.Gio.Interfaces.Converter.converterConvert' anymore. At this time you can only
-- free the object or call 'GI.Gio.Interfaces.Converter.converterReset' to reset it to the
-- initial state.
-- 
-- If the flag 'GI.Gio.Flags.ConverterFlagsFlush' is set then conversion is modified
-- to try to write out all internal state to the output. The application
-- has to call the function multiple times with the flag set, and when
-- the available input has been consumed and all internal state has
-- been produced then 'GI.Gio.Enums.ConverterResultFlushed' (or 'GI.Gio.Enums.ConverterResultFinished' if
-- really at the end) is returned instead of 'GI.Gio.Enums.ConverterResultConverted'.
-- This is somewhat similar to what happens at the end of the input stream,
-- but done in the middle of the data.
-- 
-- This has different meanings for different conversions. For instance
-- in a compression converter it would mean that we flush all the
-- compression state into output such that if you uncompress the
-- compressed data you get back all the input data. Doing this may
-- make the final file larger due to padding though. Another example
-- is a regexp conversion, where if you at the end of the flushed data
-- have a match, but there is also a potential longer match. In the
-- non-flushed case we would ask for more input, but when flushing we
-- treat this as the end of input and do the match.
-- 
-- Flushing is not always possible (like if a charset converter flushes
