gFileInputStreamQueryInfoAsync {RGtk2} | R Documentation

## gFileInputStreamQueryInfoAsync

### Description

Queries the stream information asynchronously. When the operation is finished `callback` will be called. You can then call `gFileInputStreamQueryInfoFinish` to get the result of the operation.

### Usage

    gFileInputStreamQueryInfoAsync(object, attributes, io.priority = 0,
        cancellable = NULL, callback, user.data = NULL)

### Arguments

``object`` | a `GFileInputStream`.
``attributes`` | a file attribute query string.
``io.priority`` | the I/O priority of the request.
``cancellable`` | optional `GCancellable` object, `NULL` to ignore.
``callback`` | callback to call when the request is satisfied
``user.data`` | the data to pass to callback function

### Details

For the synchronous version of this function, see `gFileInputStreamQueryInfo`.

If `cancellable` is not `NULL`, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error `G_IO_ERROR_CANCELLED` will be set
