a buffer to write data from
the size of the buffer. If -1, the buffer is taken to be a nul-terminated string.
The number of bytes written. This can be nonzero even if the return value is not %G_IO_STATUS_NORMAL. If the return value is %G_IO_STATUS_NORMAL and the channel is blocking, this will always be equal to @count if @count >= 0.
Return: the status of the operation.
GException on failure.
Replacement for g_io_channel_write() with the new API.
On seekable channels with encodings other than %NULL or UTF-8, generic mixing of reading and writing is not allowed. A call to g_io_channel_write_chars () may only be made on a channel from which data has been read in the cases described in the documentation for g_io_channel_set_encoding ().
