public abstract ssize_t write (uint8 buffer, Cancellable? cancellable = null) throws IOError
Tries to write
buffer.length bytes from
buffer into the stream.
Will block during the operation.
If count is 0, returns 0 and does nothing. A value of
buffer.length larger than g_maxssize will
cause a g_io_error_invalid_argument error.
On success, the number of bytes written to the stream is returned. It is not an error if this is not the same as the requested size, as it can
happen e.g. on a partial I/O error, or if there is not enough storage in the stream. All writes block until at least one byte is written or an
error occurs; 0 is never returned (unless
buffer.length is 0).
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.
If an operation was partially finished when the operation was cancelled the partial result will be returned, without an error.
On error -1 is returned and throws is set accordingly.
