|

|
|
C*
|
||
|
|
C* Remove an exit program from the exit point and then deregister
|
||
|
|
C* the exit point. It is not necessary to remove exit programs
|
||
|
|
C* from an exit point before deregistering the exit point. It is
|
||
|
|
C* done here only for illustrative purposes.
|
||
|
|
C*
|
||
|
|
C* Initialize the error code parameter. To signal exceptions to
|
||
|
|
C* this program by the API, you need to set the bytes provided
|
||
|
|
C* field of the error code to zero. Because this program has
|
||
|
|
C* exceptions sent back through the error code parameter, it sets
|
||
|
|
C* the bytes provided field to the number of bytes it gives the
|
||
|
|
C* API for the parameter.
