17 A virtual stream (TCP/IP) connection is established with the server
18 specified by server.
19
20 This function must be called before any of the other pbs_ functions.
21 They will transmit their batch requests over the connection established
22 by this function. Multiple requests may be issued over the connection
23 before it is closed.
24
25 The connection should be closed by a call to pbs_disconnect() when all
26 requests have been sent to the server.
27
28 The parameter, server, is of the form host_name[:port], see section
29 2.7.9. If port is not specified, the standard PBS port number will be
30 used.
31
32 If the parameter, server, is either the null string or a null pointer,
33 a connection will be opened to the default server. The default server
34 is defined by (a) the setting of the environment variable PBS_DEFAULT
35 which contains a destination, or (b) the destination in the batch
36 administrator established file {PBS_DIR}/default_destn.
37
38 The variable pbs_server, declared in pbs_ifl.h, is set on return to
39 point to the server name to which pbs_connect() connected or attempted
40 to connect.

52 When the connection to batch server has been successfully created, the
53 routine will return a connection identifier which is positive. Other‐
54 wise, a negative value is returned. The error number is set in
55 pbs_errno.
