readUint32
open fun readUint32(cancellable: Cancellable? = null): <Error class: unknown class><<Error class: unknown class>>
Reads an unsigned 32-bit/4-byte value from @stream.
In order to get the correct byte order for this read operation, see g_data_input_stream_get_byte_order() and g_data_input_stream_set_byte_order().
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.
Return
an unsigned 32-bit/4-byte value read from the @stream or 0 if an error occurred.
Parameters
cancellable
optional #GCancellable object, null to ignore.
