[gnet-dev] am i wrong? gnet_io_channel_readline

[richard_III gmx net]

i'd like to write a server using gnet. the server does read what the client
types by using gnet_io_channel_readline or gnet_io_channel_readline_strdup.
both of those methodes are working. the problem is, the cpu usage is to
much. if i have 0 clients connected the useage is correctly by 0% for this
process. if i have 1 client connected the useg increases up to 50% for the
2nd client up to 99%.

the following code runs in a thread-methode.

\/
guint bytes_read;
gchar* rbuffer;

while (true)
{
  bytes_read = 0;

  gnet_io_channel_readline_strdup (m_pCh,&rbuffer,&bytes_read);
}
/\

any idea what i did wrong?
thanks
richard
