Purpose
|
Searches for the next data descriptor that matches the specified tag and reference number. |
|
Return value
|
Returns SUCCEED (or 0) if successful and FAIL (or -1) otherwise. |
|
Description
|
Wildcards apply. If origin is DF_START, the search will start at the beginning of the data descriptor list. If origin is DF_CURRENT, the search will begin at the current position. Searching backwards from the end of a data descriptor list is not yet implemented. |

|
If the search is successful, the access identifier reflects the new data element, otherwise it is not modified. |
