Description

The DbEnv::txn_stat method creates a statistical structure and copies a pointer to it into a user-specified memory location.

Statistical structures are created in allocated memory. If db_malloc is non-NULL, it is called to allocate the memory; otherwise, the library function malloc(3) is used. The function db_malloc must match the calling conventions of the malloc(3) library routine. Regardless, the caller is responsible for deallocating the returned memory. To deallocate returned memory, free the returned memory reference, references inside the returned memory ...
