OutputStream.writevAll

Tries to write the bytes contained in the @n_vectors @vectors into the stream. Will block during the operation.

This function is similar to g_output_stream_writev(), except it tries to write as many bytes as requested, only stopping on an error.

On a successful write of all @n_vectors vectors, %TRUE is returned, and @bytes_written is set to the sum of all the sizes of @vectors.

If there is an error during the operation %FALSE is returned and @error is set to indicate the error status.

As a special exception to the normal conventions for functions that use #GError, if this function returns %FALSE (and sets @error) then @bytes_written will be set to the number of bytes that were successfully written before the error was encountered. This functionality is only available from C. If you need it from another language then you must write your own loop around g_output_stream_write().

The content of the individual elements of @vectors might be changed by this function.
