int cs_connect(COMSTACK handle, void *address);
Initiate a connection with the target at address (more on addresses below). The function will return 0 on success, and 1 if the operation does not complete immediately (this will only happen on a nonblocking endpoint). In this case, use cs_rcvconnect to complete the operation, when select(2) or poll(2) reports input pending on the association.
int cs_rcvconnect(COMSTACK handle);
Complete a connect operation initiated by cs_connect(). It will return 0 on success; 1 if the operation has not yet completed (in this case, call the function again later); -1 if an error has occurred.
