Function

Giopollable_stream_write_all

Declaration

gboolean
g_pollable_stream_write_all (
  GOutputStream* stream,
  void* buffer,
  gsize count,
  gboolean blocking,
  gsize* bytes_written,
  GCancellable* cancellable,
  GError** error
)

Description

Tries to write count bytes to stream, as with g_output_stream_write_all(), but using g_pollable_stream_write() rather than g_output_stream_write().

On a successful write of count bytes, TRUE is returned, and bytes_written is set to count.

If there is an error during the operation (including G_IO_ERROR_WOULD_BLOCK in the non-blocking case), FALSE is returned and error is set to indicate the error status, bytes_written is updated to contain the number of bytes written into the stream before the error occurred.

As with g_pollable_stream_write(), if blocking is FALSE, then stream must be a GPollableOutputStream for which g_pollable_output_stream_can_poll() returns TRUE or else the behavior is undefined. If blocking is TRUE, then stream does not need to be a GPollableOutputStream.

Parameters

`stream`	`GOutputStream`
	A `GOutputStream`.
	The data is owned by the caller of the function.
`buffer`	An array of `guint8`
	The buffer containing the data to write.
	The length of the array is specified in the `count` argument.
	The data is owned by the caller of the function.
`count`	`gsize`
	The number of bytes to write.
`blocking`	`gboolean`
	Whether to do blocking I/O.
`bytes_written`	`gsize*`
	Location to store the number of bytes that was written to the stream.
	The argument will be set by the function.
`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:	`gboolean`
	`TRUE` on success, `FALSE` if there was an error.
