process_peer_string()

static void process_peer_string ( void *  cls, const char *  address, int  res  )

static

Function called with a textual representation of an address.

This function will be called several times with different possible textual representations, and a last time with address being NULL to signal the end of the iteration. Note that address NULL always is the last call, regardless of the value in res.

Parameters

cls	closure
address	NULL on end of iteration, otherwise 0-terminated printable UTF-8 string, in particular an empty string if res is GNUNET_NO
res	result of the address to string conversion: if GNUNET_OK: conversion successful if GNUNET_NO: address was invalid (or not supported) if GNUNET_SYSERR: communication error (IPC error)
