.B int pbs_relnodesjob (int connect, char *job_id, char *node_list, char *extend)

.SH DESCRIPTION
Issue a batch request to release some or all of the vnodes not on the primary 
execution host that are assigned to a batch job.
.LP
A
.I "RelnodesJob"
batch request is generated and sent to the server over the connection
specified by
.I connect, 
which is the return value of \f3pbs_connect\f1().
.LP
The argument,
.I job_id,
identifies the job whose vnodes are to be released;
it is specified in the form:
.RS 4
.I "<sequence number>.<server>"
.RE
.LP
The parameter,
.I node_list,
is a list of vnode names separated by plus signs ("+") whose parent MoM is not the
MoM on the primary execution host.  If 
.I node_list
is NULL, it refers to all the vnodes that are not on the primary
execution host that are assigned to the job.

The parameter,
.I extend,
is reserved for implementation-defined extensions.
