int
db_env_set_func_sleep(int (*func_sleep)(u_long seconds, u_long microseconds));
Description
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 db_env_set_func_sleep interface affects the entire application, not a single
database or database environment.
While the db_env_set_func_sleep 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_sleep function returns a non-zero error value on failure and 0 on success.
