<p>The Get Export (QleGetExp) API allows the caller to resolve a pointer to an
|
||
|
|
export (either data or procedure) either by name or export number. The pointer
|
||
|
|
is materialized for the specified activation. If the activation mark given is
|
||
|
|
zero, then all activations in the activation group are searched (no guaranteed
|
||
|
|
search order). The QleGetExp API is identical to the
|
||
|
|
<a href="qlegetexpl.htm">Get Export Long</a> (QleGetExpLong) API, except that the QleGetExpLong API takes a
|
||
|
|
BINARY(8) activation mark as the first parameter instead of a BINARY(4)
|
||
|
|
activation mark.</p>
