NULL pointer feature of OCIAQDeq

 Hi all,

In the documentation for OCIAQDeq() it states:

"The application may choose to pass NULL for payload the first time OCIAQDeq() is called, and let the OCI allocate the memory for the payload. It can then use a pointer to that previously allocated memory in subsequent calls to OCIAQDeq() ."


Does anyone have an example of how to do this, or what it means? Once I have passed in NULL, where do I then get the pointer from?


Thanks!
