Brief_I/O

 
   Variable  I/O  Description 
   --------  ---  -------------------------------------------------- 
   handle     I   Handle of EK file. 
 

Detailed_Input

 
   handle         is a file handle returned by eklef_c. 
 

Detailed_Output

 
   None.  See $Particulars for a description of the effect of this 
   routine. 
 

Parameters

 
   None. 
 

Exceptions

 
   1)  Unloading a file that is not loaded has no effect. 
 

Files

 
   This routine unloads a binary EK file from the EK query system. 
 

Particulars

 
   This routine removes information about an EK file from the 
   EK system, freeing space to increase the number of other EK 
   files that can be loaded.  The file is also unloaded from 
   the DAS system and closed. 
 

Examples

 
   1)  Load 25 EK files sequentially, unloading the previous file 
       before each new file is loaded.  Unloading files prevents 
       them from being searched during query execution. 
 
          for ( i = 0;  i < 25;  i++ )
          {
             eklef_c ( ek[i], &handle );
 
             [Perform queries] 
 
             ekuef_c ( handle );
          }
