.SH NAME
pbs_statque - obtain status of PBS batch queues
.SH SYNOPSIS
#include <pbs_error.h>
.br
#include <pbs_ifl.h>
.sp
.B struct batch_status *pbs_statque(\^int\ connect, char\ *id, struct\ attrl\ *attrib, char\ *extend)
.sp
.B void pbs_statfree(\^struct batch_status *psj\^)

.SH DESCRIPTION
Issue a batch request to obtain the status of a batch queue.
.LP
A
.I "Status Queue"
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 
.I id
is the name of a queue, in the form:
.RS 4
.I queue_name
.RE
or the null string.  If
.I queue_name
is specified, the status of the queue named
.I queue_name
at the server is returned.  If the
.I id
is a null string or null pointer, the status of all
queues at the server is returned.
.LP
The parameter,
.I attrib ,
is a pointer to an
.I attrl 
structure which is defined in pbs_ifl.h as:
.sp
.Ty
.nf
    struct attrl {
        struct attrl *next;
        char         *name;
        char         *resource;
        char         *value;
    };
.fi
.sp
The
.I attrib
list is terminated by the first entry where
.I next
is a null pointer.  If 
.I attrib
is given, then only the attributes in the list are returned by the server.
Otherwise, all the attributes of a queue are returned.
When an
.I attrib
list is specified, the
.I name
member is a pointer to an attribute name as listed in pbs_alterjob(3B) and
pbs_submit(3B).  The
.I resource
member is only used if the name member is ATTR_l, otherwise it should be a
pointer to a null string.
The
.I value
member should always be a pointer to a null string.
.LP
When 
.B pbs_statque 
is used to get the attributes of an object, a single 
.I attrl 
data structure is returned for each parameterized attribute.
.LP
The parameter,
.I extend ,
is reserved for implementation-defined extensions.
.LP
The return value is a pointer to a list of
.I batch_status
structures, which is defined in pbs_ifl.h as:
.sp
.Ty
.nf
    struct batch_status {
        struct batch_status *next;
        char                *name;
        struct attrl        *attribs;
        char                *text;
    }
.fi
.LP
It is up the user to free the structure when no longer needed, by calling
\f3pbs_statfree\f1().
.LP
.SH "SEE ALSO"
qstat(1B) and pbs_connect(3B)
.SH DIAGNOSTICS
When the batch request generated by \f3pbs_statque\f1()
function has been completed successfully by a batch server, the routine will
return a pointer to the batch_status structure.
Otherwise, a null pointer is returned and the error code
is set in the global integer pbs_errno.
