Method

GioDataInputStreamread_int64

Declaration

gint64
g_data_input_stream_read_int64 (
  GDataInputStream* stream,
  GCancellable* cancellable,
  GError** error
)

Description

Reads a 64-bit/8-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.

Parameters

`cancellable`	`GCancellable`
	Optional `GCancellable` object, `NULL` to ignore.
	The argument can be `NULL`.
	The data is owned by the caller of the function.
`error`	`GError **`
	The return location for a `GError*`, or `NULL`.

Return value

Returns:	`gint64`
	A signed 64-bit/8-byte value read from `stream` or `0` if an error occurred.
