pbs_statque

NAME

pbs_statque - obtain status of pbs batch queues

SYNOPSIS

#include <pbs_error.h>
#include <pbs_ifl.h>

 struct batch_status *pbs_statque(int connect, char *id,
 struct attrl *attrib, 
 char *extend)
 
 void pbs_statfree(struct batch_status *psj)
 

DESCRIPTION

Issue a batch request to obtain the status of a batch queue.

A Status Queue batch request is generated and sent to the server over the connection specified by connect which is the return value of pbs_connect().

The id is the name of a queue, in the form:

or the null string. If is specified, the status of the queue named at the server will be returned. If the id is a null string or null pointer, the status of all queues at the server will be returned.

The parameter, attrib is a pointer to an attrl structure which is defined in pbs_ifl.h as:

     struct attrl {
         struct attrl *next;
         char         *name;
         char         *resource;
         char         *value;
     };
 

The attrib list is terminated by the first entry where is a null pointer. If attrib is given, then only the attributes in the list are returned by the server. Otherwise, all the attributes of a job are returned. When an attrib list is specified, the member is a pointer to a attribute name as listed in pbs_alter(3) and pbs_submit(3). The member is only used if the name member is ATTR_l, otherwise it should be a pointer to a null string. The member should aways be a pointer to a null string.

The parameter, extend is reserved for implementation defined extensions.

The return value is a pointer to a list of batch_status structures, which is defined in pbs_ifl.h as:

     struct batch_status {
         struct batch_status *next;
         char                *name;
         struct attrl        *attribs;
         char                *text;
     }
 

It is up the user to free the structure when no longer needed, by calling pbs_statfree().

DIAGNOSTICS

When the batch request generated by pbs_statque() 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.
