Function Documentation

int xbt_socket_my_port

(

xbt_socket_t

sock

)

Get the port number on which this socket is connected on my side

int xbt_socket_peer_port

(

xbt_socket_t

sock

)

Get the port number on which this socket is connected on remote side.

This is the port declared on remote side with the gras_socket_master() function (if any, or a random number being unique on the remote host). If remote used gras_socket_master() more than once, the lastly declared number will be used here.

Note to BSD sockets experts: With BSD sockets, the sockaddr structure allows you to retrieve the port of the client socket on remote side, but it is of no use (from user perspective, it is some random number above 6000). That is why XBT sockets differ from BSD ones here.

const char* xbt_socket_peer_name

(

xbt_socket_t

sock

)

Get the host name of the remote side

const char* xbt_socket_peer_proc

(

xbt_socket_t

sock

)

Get the process name of the remote side
