pbs_statnode – obtain status of pbs nodes
Synopsis
#include <pbs_error.h>
#include <pbs_ifl.h> struct batch_status *pbs_statnode(int connect, char
Description
Issue a batch request to obtain the status of a PBS node or nodes. A Status Node batch request is generated and sent to the server over the connection specified by which is the return value of pbs_connect(). The is the name of a node or the null string. If specifies a node name, the status of that node will be returned. If the is a null string (or null pointer), the status of all nodes at the server will be returned. In TORQUE 2.1.0, if the starts with a ":" and followed by a node property, all nodes with that property are returned; creating a "node group" functionality. The string ":ALL" is specially handled and is the same as passing a null string. The parameter, is a pointer to an attrl structure which is defined in pbs_ifl.h as: The list is terminated by the first entry where is a null pointer. If is given, then only the attributes in the list are returned by the server. Otherwise, all the attributes of a node are returned. When an list is specified, the member is a pointer to a attribute name. The supported attribute names relating to nodes are "state", "properties", "np", "ntype", "jobs", "status", and "note". The member is not used and must be a pointer to a null string. The member should aways be a pointer to a null string. The parameter, 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: 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_statnode() 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.
