The following patches allows a user to track: 1) heap creation 2) heap destruction 3) allocation/freeing of dynamic memory and 4) reallocation of dynamic memory (i.e. realloc functionality) Included is the CDL to control it. By default it is turned off. There will be a performance penalty to turn on the logging ability even if you do not use it since a pointer must be checked (the callback). Example usage is: // varriable sized heaps Cyg_Mempool_Variable::set_create_cb (var_create); Cyg_Mempool_Variable::set_destroy_cb (var_destroy); Cyg_Mempool_Variable::set_pre_alloc_cb (var_pre_alloc); Cyg_Mempool_Variable::set_post_alloc_cb (var_post_alloc); Cyg_Mempool_Variable::set_pre_free_cb (var_pre_free); Cyg_Mempool_Variable::set_post_free_cb (var_post_free); // dlmalloc heaps Cyg_Mempool_dlmalloc::set_create_cb (var_create); Cyg_Mempool_dlmalloc::set_destroy_cb (var_destroy); Cyg_Mempool_dlmalloc::set_pre_alloc_cb (var_pre_alloc); Cyg_Mempool_dlmalloc::set_post_alloc_cb (var_post_alloc); Cyg_Mempool_dlmalloc::set_pre_free_cb (var_pre_free); Cyg_Mempool_dlmalloc::set_post_free_cb (var_post_free); // fixed size block allocator heaps Cyg_Mempool_Fixed::set_create_cb (fix_create); Cyg_Mempool_Fixed::set_destroy_cb (fix_destroy); Cyg_Mempool_Fixed::set_pre_alloc_cb (fix_pre_alloc); Cyg_Mempool_Fixed::set_post_alloc_cb (fix_post_alloc); Cyg_Mempool_Fixed::set_pre_free_cb (fix_pre_free); Cyg_Mempool_Fixed::set_post_free_cb (fix_post_free); The additional functionality will allow a user to keep track of every allocation in the system, as well as to modify allocated memory to add padding to detect array overflows.
