Name
prt_api_req_class_itemlist_Ex
Purpose
Request list of item tracking data.
Description:
This routine provides a mechanism to request the Item Tracking Data for one or more Items of a particular Item Class from the PRT Data Server (PRT_DS) residing within all configured PRT services, a specific PRT service, a specific Tracking Group, a specific Tracking Region, or at a specific location within a specific Tracking Region. If the request is a success the calling routine will receive back a count of the number of items returned to the item list. If the request fails, the calling routine will receive back status information on the reason for the failure.

Arguments
|
Argument |
Description |
|
Input |
|
|
prt_svc_id |
PRT service identifier (optional, but required if no other arguments specified) |
|
group_id |
Identifier of the group. (optional, but required if no other arguments specified) |
|
region_id |
Identifier of the region. (optional, but required if no other arguments specified, required if region location specified) Note: At least one of the above three arguments must be specified. If not, all services will be queried. It is possible that a list of 'items' will be collected, but not all services will have responded (because one or more of them were down). Thus the user has a list of valid responses, but may not have ALL the 'items' that should have been returned. In this case, the function will return COR_WARNING with an err_code of PRTI_NOT_ALL_SVCS_RESPONDED. The function returns, through an argument passed, the number of 'items' actually received. This argument will show how many valid 'items' were received. |
|
region_loc |
Specific location in the region (required). If all items within a region are being requested, the region_loc must be specified as ALL_LOCATIONS. Otherwise a specific location requests items at only that location. |
|
Item_class_id |
Filter to use to select a particular class. Enter a blank to select all items (that is for no filtering). |
|
Search_flag |
If search_flag is 0 then item are searched in the default project if any default is set already and if not found then other configured projects are searched. For setting a project as default project we can use prt_api_cur_project. |
|
Output |
|
|
*item_count |
Count of Items returned to schema |
|
*max_location |
Location number of the highest populated location in the region, regardless of the Item Class in the region. |
|
*retstat |
Pointer to COR_STATUS structure |
Return Value
Either COR_SUCCESS, COR_WARNING or COR_FAILURE.
If the function returns COR_WARNING or COR_FAILURE, additional error information can be found in the COR_STATUS structure.
