InputStream.skipAsync
void skipAsync(size_t count, int ioPriority, gio.cancellable.Cancellable cancellable = null, gio.types.AsyncReadyCallback callback = null)Request an asynchronous skip of count bytes from the stream. When the operation is finished callback will be called. You can then call [gio.input_stream.InputStream.skipFinish] to get the result of the operation.
During an async request no other sync and async calls are allowed, and will result in [gio.types.IOErrorEnum.Pending] errors.
A value of count larger than G_MAXSSIZE will cause a [gio.types.IOErrorEnum.InvalidArgument] error.
On success, the number of bytes skipped 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 skip 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 [glib.types.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.
Parameters
count | the number of bytes that will be skipped from the stream |
ioPriority | the [I/O priority][io-priority] of the request |
cancellable | optional #GCancellable object, null to ignore. |
callback | a #GAsyncReadyCallback to call when the request is satisfied |
