Format
ANSI C, C++
#include <dcadm.h> int dc_adm_get_sv_status_begin (char *node_id, DCLONG *entry_count, DCLONG flags) |

#include <dcadm.h> int dc_adm_get_sv_status_begin (node_id, entry_count, flags) char *node_id; DCLONG *entry_count; DCLONG flags; |
Description
The function dc_adm_get_sv_status_begin() starts acquiring the statuses of user servers at a specified node identifier. When this function terminates normally, it returns the number of user servers whose status is to be acquired.
Arguments whose value is set in the UAP
node_id
Specify the pointer to the node identifier or the character string (*). Add a null character after the node identifier. If the pointer to the character string (*) is specified, the OpenTP1 node which called this function is assumed.
The length of the node identifier must be equal to the length defined by DCADM_NODE_ID_LEN. If a node identifier with a different length is specified, the function returns with an error.
entry_count
Specify the pointer to the area to which the number of user servers will be returned. The area set here will contain the number of user servers at the OpenTP1 node identified by node_id.
flags
Specify DCNOFLAGS.
Return values
Return value | Return value (numeric) | Explanation |
---|---|---|
DC_OK | 0 | Normal termination. The area indicated by entry_count now contains the number of user servers. |
DCADMER_PARAM | -1852 | The value specified for the argument is invalid. |
DCADMER_COMM | -1851 | Communication with the specified OpenTP1 node is impossible for the following reason:
|
DCADMER_MEMORY | -1861 | The memory became insufficient. |
DCADMER_PROTO | -1854 | The function dc_adm_get_sv_status_begin() was already called. |
The function dc_rpc_open() was not called. | ||
DCADMER_MULTI_DEF | -1864 | N is specified for multi_node_option in the system common definition. |
The TP1/Multi is not installed in the system. | ||
The correct version TP1/Multi is not installed in the system. | ||
DCADMER_DEF | -1862 | An incorrect value is specified in the multinode configuration definition or in the multinode physical definition. |
DCADMER_NODE_NOT_EXIST | -1867 | The node identified by node_id is not included in the OpenTP1 nodes. |
DCADMER_REMOTE | -1866 | The specified OpenTP1 node cannot use the multinode facility for the following reason:
|
DCADMER_SWAP | -1868 | The status of the user server cannot be acquired because the system is being switched. |
