db_env_set_func_realloc

#include <db.h> int db_env_set_func_realloc(void *(*func_realloc)(void *ptr, size_t size)); Description Replace Berkeley DB calls to the ANSI C X3.159-1989 (ANSI C) standard realloc function with func_realloc, which must conform to the standard interface. The db_env_set_func_realloc interface affects the entire application, not a single database or database environment. Although the db_env_set_func_realloc 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_realloc function returns a non-zero error value on failure and 0 on success. Errors The db_env_set_func_realloc function may fail and return a non-zero error for the following conditions: EINVAL An invalid flag value or parameter was specified. The db_env_set_func_realloc function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions. If a catastrophic error has occurred, the db_env_set_func_realloc function may fail and return DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail in the same way.
