 _itemReturn()
 Return an Item to CA-Clipper
------------------------------------------------------------------------------
 C Prototype

     #include "item.api"
     ITEM _itemReturn(
                       ITEM itemRet
                     )

 Arguments

     itemRet is the Item you wish to return to CA-Clipper.

 Returns

     The same ITEM that was posted as the return value.

 Description

     The _itemReturn() function is used to send an Item back to CA-Clipper in
     the form of a return value.

     Note:  Once an Item is returned to CA-Clipper via _itemReturn(), it
     is considered as "referenced" by the CA-Clipper runtime, and therefore,
     not a candidate for garbage collection.  However, your C function must
     still call _itemRelease() after posting an item for return so that once
     the CA-Clipper variable which received the return value goes out of
     scope, it does get properly collected.

 Examples

     /*
     *
     * CharCount( cString, cChar )
     *
     * Count occurrences of a single character
     * in a CA-Clipper string.  Version 1.00
     *

           return;               // Early return!
