-- t'GI.Gio.Objects.InputStream.InputStream' has functions to read from a stream ('GI.Gio.Objects.InputStream.inputStreamRead'),
-- to close a stream ('GI.Gio.Objects.InputStream.inputStreamClose') and to skip some content
-- ('GI.Gio.Objects.InputStream.inputStreamSkip').
-- 
-- To copy the content of an input stream to an output stream without
-- manually handling the reads and writes, use 'GI.Gio.Objects.OutputStream.outputStreamSplice'.
-- 
-- See the documentation for t'GI.Gio.Objects.IOStream.IOStream' for details of thread safety of
-- streaming APIs.
-- 
-- All of these functions have async variants too.

-- | Request an asynchronous read of /@count@/ bytes from the stream into the buffer
-- starting at /@buffer@/. When the operation is finished /@callback@/ will be called.
-- You can then call 'GI.Gio.Objects.InputStream.inputStreamReadFinish' to get the result of the
-- operation.
-- 
-- During an async request no other sync and async calls are allowed on /@stream@/, and will
-- result in 'GI.Gio.Enums.IOErrorEnumPending' errors.
-- 
-- A value of /@count@/ larger than @/G_MAXSSIZE/@ will cause a 'GI.Gio.Enums.IOErrorEnumInvalidArgument' error.
-- 
-- On success, the number of bytes read into the buffer will be passed to the
-- callback. It is not an error if this is not the same as the requested size, as it
-- can happen e.g. near the end of a file, but generally we try to read
-- as many bytes as requested. Zero is returned on end of file
-- (or if /@count@/ is zero),  but never otherwise.
-- 
-- Any outstanding i\/o request with higher priority (lower numerical value) will
-- be executed before an outstanding request with lower priority. Default
-- priority is 'GI.GLib.Constants.PRIORITY_DEFAULT'.
-- 
-- The asynchronous methods have a default fallback that uses threads to implement
-- asynchronicity, so they are optional for inheriting classes. However, if you
-- override one you must override all.

-- | Request an asynchronous read of /@count@/ bytes from the stream into a

-- called. You can then call 'GI.Gio.Objects.InputStream.inputStreamReadBytesFinish' to get the
-- result of the operation.
-- 
-- During an async request no other sync and async calls are allowed
-- on /@stream@/, and will result in 'GI.Gio.Enums.IOErrorEnumPending' errors.
-- 
-- A value of /@count@/ larger than @/G_MAXSSIZE/@ will cause a
-- 'GI.Gio.Enums.IOErrorEnumInvalidArgument' error.
-- 
-- On success, the new t'GI.GLib.Structs.Bytes.Bytes' will be passed to the callback. It is
-- not an error if this is smaller than the requested size, as it can
-- happen e.g. near the end of a file, but generally we try to read as
-- many bytes as requested. Zero is returned on end of file (or if
-- /@count@/ is zero), but never otherwise.
-- 
-- Any outstanding I\/O request with higher priority (lower numerical
-- value) will be executed before an outstanding request with lower
-- priority. Default priority is 'GI.GLib.Constants.PRIORITY_DEFAULT'.
