#include <db.h>int DBENV->set_func_sleep(DB_ENV *dbenv, int (*func_sleep)(u_long seconds, u_long microseconds));
The Berkeley DB library requires the ability to cause a process to suspend itself for a period of time, relinquishing control of the processor to any other waiting thread of control. The func_sleep argument must conform to the following interface:
int sleep(u_long seconds, u_long microseconds);
The seconds and microseconds arguments specify the amount of time to wait until the suspending thread of control should run again.
The seconds and microseconds arguments may not be normalized when the sleep function is called, i.e., the microseconds argument may be greater than 1000000.
The func_sleep function must return the value of errno on failure and 0 on success.
The DBENV->set_func_sleep interface affects the entire application, not only the environment in which it is called.
The DBENV->set_func_sleep interface may only be used to configure Berkeley DB before the DBENV->open interface is called.
The DBENV->set_func_sleep function returns a non-zero error value on failure and 0 on success.
Called after DBENV->open was called.
