[PD-dev] help with sys_addpollfn and friends

[Miller Puckette]

The simplest example is in the netreceive object (x_net.c in the Pd
source)... you open a socket and call sys_addpollfn to have a callback
function added to it.  The callback function gets called from the Pd
scheduler whenever select() reports that the socket (or other selectable
file descriptor) can be read without blocking.  Be sure to call
sys_rmpollfn() when you're deleted so the callbacks stop coming..

cheers
Miller
