Berkeley DB: db_env_set_func_sleep
db_env_set_func_sleep
|
 |
#include <db.h>
int
db_env_set_func_sleep(int (*func_sleep)(u_long seconds, u_long microseconds));
Description: db_env_set_func_sleep
The Berkeley DB library requires the ability to cause a thread of control to
suspend itself for a period of time, relinquishing control of the
processor to any other waiting thread of control.
The db_env_set_func_sleep method configures all operations performed by a process and
all of its threads of control, not operations confined to a single
database environment.
Although the db_env_set_func_sleep method may be called at any time during the life of
the application, it should normally be called before making calls to the
db_env_create or db_create methods.
The db_env_set_func_sleep method
returns a non-zero error value on failure
and 0 on success.
Parameters
- func_sleep
- The func_sleep parameter is the function which seeks to a specific
location in a file.
The seconds and microseconds parameters specify the amount
of time to wait until the suspending thread of control should run again.
The seconds and microseconds parameters may not be
normalized when the sleep function is called; that is, the
microseconds parameter may be greater than 1000000.
The func_sleep function must return the value of errno on
failure and 0 on success.
