Member Function Documentation

int ACE_Based_Pointer_Repository::bind (  void *  addr,
size_t  size
) 
 

Bind a new entry to the repository or update the size of an existing entry. Returns 0 on success and -1 on failure.

00086 }

int ACE_Based_Pointer_Repository::find (  void *  addr,
void *&  base_addr
) 
 

Return the appropriate base_addr region that contains addr. Returns 1 on success and 0 if the addr isn't contained in any base_addr region.
