DBENV->set_func_write

APIRef

#include <db.h>

int DBENV->set_func_write(DB_ENV *dbenv, ssize_t (*func_write)(int fd, const void *buffer, size_t nbytes));

Description

Replace Berkeley DB calls to the IEEE/ANSI Std 1003.1 (POSIX) write function with func_write, which must conform to the standard interface.

The DBENV->set_func_write interface affects the entire application, not only the environment in which it is called.

The DBENV->set_func_write interface may only be used to configure Berkeley DB before the DBENV->open interface is called.

The DBENV->set_func_write function returns a non-zero error value on failure and 0 on success.

Errors

EINVAL
An invalid flag value or parameter was specified.

Called after DBENV->open was called.
