Function Documentation

int getArgs (  int  argc, char *  argv[], char **  helper_ip, port_t *  helper_port, char **  peer_ip, port_t *  peer_port, char **  buddy_ext_ip, char **  buddy_int_ip, port_t *  buddy_int_port, char **  dev, char **  msg, flag_t *  random )

gets arguments from the command line uses errorcodes.h for error codes Parameters: argc  the number of arguments passed in argv  the vector of arguments helper_ip  a pointer to a pointer. When finished, will point to a string with the helper's dotted-decimal IP address helper_port  pointer to the helper's port (will be filled in) peer_ip  a pointer to a pointer. When finished, will point to a string with the peer's dotted-decimal IP address peer_port  pointer to the peer's starting port (will be filled in) buddy_ext_ip  a pointer to a pointer. When finished, will point to a string with the buddy's dotted-decimal external IP address buddy_int_ip  a pointer to a pointer. When finished, will point to a string with the buddy's dotted-decimal internal IP address buddy_int_port  pointer to the buddy's starting port (will be filled in) dev  a pointer to a pointer. When finished, will point to a string with the network device to use. If none is specified, will be NULL on function return msg  a pointer to a pointer. When finished, will point to a string with the message to send to the buddy. random  a pointer to an flag_t to set to 1 if the peer wants to be random. Returns: SUCCESS, neg value on failure Definition at line 160 of file peer.c.

Referenced by main().

int main (  int  argc, char *  argv[] )

entry point for peer stub application Parameters: argc  the number of elements in the argument vector argv  the argument vector return 0 on success, neagive on failure Definition at line 87 of file peer.c.

prints the program use Returns: void
