read

open fun read(cancellable: Cancellable? = null): <Error class: unknown class><FileInputStream>

Opens a file for reading. The result is a #GFileInputStream that can be used to read the contents of the file.

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 returned.

If the file does not exist, the %G_IO_ERROR_NOT_FOUND error will be returned. If the file is a directory, the %G_IO_ERROR_IS_DIRECTORY error will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on.

Return

#GFileInputStream or null on error. Free the returned object with g_object_unref().

Parameters

cancellable

a #GCancellable
