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


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.

Available since: 2.34



Type: GOutputStream

A GOutputStream.

The data is owned by the caller of the function.

Type: 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.

Type: gsize

The number of bytes to write.


Type: gboolean

Whether to do blocking I/O.


Type: gsize*

Location to store the number of bytes that was written to the stream.

The argument will be set by the function.

Type: GCancellable

Optional GCancellable object, NULL to ignore.

The argument can be NULL.
The data is owned by the caller of the function.

Type: GError **

The return location for a recoverable error.

The argument can be NULL.
If the return location is not NULL, then you must initialize it to a NULL GError*.
The argument will left initialized to NULL by the function if there are no errors.
In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: gboolean

TRUE on success, FALSE if there was an error.
