Expand description

If this flag is set, then a leaner wrapping mechanism is used with lower overhead. However, several features are not supported with this flag:

  • Only one wrap request per address is allowed. A second request will fail, even if an earlier request was unwrapped, unless the same pre and post callback functions are used.
  • Wrapping should occur prior to any execution (e.g., at startup or module load time). A new wrap request that occurs between the pre and post wrap points may have its post callback called even though its pre callback was never called.
  • Unwrapping should only happen on module unload. It is not supported between a pre and post callback. Only set this flag if you are certain that all uses of wrapping in your client and all libraries it uses can abide the above restrictions. Once set, this flag cannot be unset.
