MyParamDestructor

Destroys a parameter.

void MyParamDestructor (Environment* ev, 
void* param);

A pointer to the SOM environment parameter used to pass exceptions.

param

A pointer to the parameter to be destroyed.

DISCUSSION

Your parameter destructor function should destroy a parameter when it is removed from a parameter set. You add a parameter and an associated destructor function to a parameter set by calling the ParameterSet::PutParameter method. Your destructor function is called either when you call the ParameterSet::RemoveParameter method to remove the parameter from the parameter set or when the parameter set is destroyed.
