db_env_set_func_malloc |
#include <db.h>int db_env_set_func_malloc(void *(*func_malloc)(size_t size));
Replace Berkeley DB calls to the ANSI C X3.159-1989 (ANSI C) standard malloc function with func_malloc, which must conform to the standard interface.
The db_env_set_func_malloc interface affects the entire application, not a single database or database environment.
While the db_env_set_func_malloc interface may be used to configure Berkeley DB at any time during the life of the application, it should normally be called before making any calls to the db_env_create or db_create functions.
The db_env_set_func_malloc function returns a non-zero error value on failure and 0 on success.
