###

    #include <db.h>

    int
    db_env_set_pageyield(int pageyield);

# Description

Yield the processor whenever requesting a page from the cache. Setting pageyield to a non-zero value causes Berkeley DB to yield the processor any time a thread requests a page from the cache.

The db_env_set_pageyield interface affects the entire application, not a single database or database environment.

While the db_env_set_pageyield 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.

This functionality should never be used for any other purpose than stress testing.

The db_env_set_pageyield interface may be used to configure Berkeley DB at any time during the life of the application.

The db_env_set_pageyield function returns a non-zero error value on failure and 0 on success.

# Errors

EINVAL
  An invalid flag value or parameter was specified.
