To fix this issue,pDaclargument should be a pointer to anACLstructure that specifies the DACL for the security descriptor.
If your code refers to a local variable, and there are no other references to it, assigning null to it might cause the object to be collected. However, this could result in a null pointer exception or alter the program's behavior. If neither of these consequences occurs, it suggests that...
