-/** Creates a host for communicating to peers.  
-
-    @param address   the address at which other peers may connect to this host.  If NULL, then no peers may connect to the host.
-    @param peerCount the maximum number of peers that should be allocated for the host.
-    @param channelLimit the maximum number of channels allowed; if 0, then this is equivalent to ENET_PROTOCOL_MAXIMUM_CHANNEL_COUNT
-    @param incomingBandwidth downstream bandwidth of the host in bytes/second; if 0, ENet will assume unlimited bandwidth.
-    @param outgoingBandwidth upstream bandwidth of the host in bytes/second; if 0, ENet will assume unlimited bandwidth.
-
-    @returns the host on success and NULL on failure
-
-    @remarks ENet will strategically drop packets on specific sides of a connection between hosts
-    to ensure the host's bandwidth is not overwhelmed.  The bandwidth parameters also determine
-    the window size of a connection which limits the amount of reliable packets that may be in transit
-    at any given time.
