.SH DESCRIPTION
A virtual stream (TCP/IP) connection is established with the server
specified by
.Ar server .
.LP
This function must be called before any of the other
.B pbs_
functions.
They will transmit their batch requests over the connection established
by this function.
Multiple requests may be issued over the connection before it is closed.
.LP
The connection should be closed by a call to \fBpbs_disconnect\fP()
when all requests have been sent to the server.
.LP
The parameter,
.Ar server ,
is of the form
.Ty host_name[:port] ,
see section 2.7.9.
If
.Ty port
is not specified, the standard PBS port number will be used.
.LP
If the parameter,
.Ar server ,
is either the null string or a null pointer,
a connection will be opened to the default server.
The default server is defined
.if !\n(Pb .ig Ig
in section \*(Si.
.Ig
.if \n(Pb .ig Ig
by (a) the setting of the environment
variable
.B PBS_DEFAULT
which contains a destination, or (b) the destination in the batch administrator
established file
.Av {PBS_DIR}/default_destn .
.Ig
.LP
The variable
.Ar pbs_server ,
declared in pbs_ifl.h,
is set on return to point to the server
name to which pbs_connect() connected or attempted to connect.
