Name

BldSendSocket - manage client socket creation

BldSendSocket() creates a client socket but doesn’t make a TCP connection.

ConnectSendSocket() causes the socket to be connected to the destination specified when the socket was created.

DestroySendSocket() closes the connection and deallocates the data structure associated with it.

These functions are part of libtcp.

They are meant to be used as part of a bigger process to manage sockets in an asyncronous way.

int BldSendSocket(
char *Hn,

char *Sn,

char *Sc,

int default_port,

char **conn,

int verbosity

);

int ConnectSendSocket(
void *conn,

int verbosity

);

int DestroySendSocket(
void *conn

);

Host name from /etc/hosts or dns lookup. This may also be specified as an IP address. If the argument is NULL, localhost will be used.

Service name from /etc/services. This may also be specified as a port number.

Service class from /etc/services.

This may be a NULL pointer. If it is then getservbyname() will return the first available entry.

Usually we specify this as "tcp" because this all AccelNET connections are "tcp" class and we aren’t interested in other classes such as "udp".

See the getservbyname() man page for more information.
