Generic interface for objects that can write data from a provided memory.
This interface allows external objects to transparently write data to this object and be notified whether more data can be written or if it's reached capacity.
Calls to Efl.Io.Writer.write() may or may not block: that's not up to this interface to specify. The user can check with event "can_write,changed" or property Efl.Io.Writer.can_write to known whenever a write could push more data.
can_write (get, set)
truewill notify Efl.Io.Writer.write can be called without blocking or failing.
Eina_Bool efl_io_writer_can_write_get(const Eo *obj); void efl_io_writer_can_write_set(Eo *obj, Eina_Bool can_write);
Writes data from a pre-populated buffer.
Eina_Error efl_io_writer_write(Eo *obj, Eina_Slice slice, Eina_Slice *remaining);
