Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

NAME
pthread_barrierattr_destroy, pthread_barrierattr_init - destroy and initialize barrier attributes object
SYNOPSIS
cc -mt [ flag... ] file... [ library... ] #include <pthread.h> int pthread_barrierattr_destroy(pthread_barrierattr_t *attr); int pthread_barrierattr_init(pthread_barrierattr_t *attr);
DESCRIPTION
The pthread_barrierattr_destroy() function destroys a barrier attributes object. A destroyed attr attributes object can be reinitialized using pthread_barrierattr_init(). The results of otherwise referencing the object after it has been destroyed are undefined. An implementa- tion can cause pthread_barrierattr_destroy() to set the object referenced by attr to an invalid value. The pthread_barrierattr_init() function initializes a barrier attributes object attr with the default value for all of the attributes defined by the implementation. Results are undefined if pthread_barrierattr_init() is called specifying an already initialized attr attributes object. After a barrier attributes object has been used to initialize one or more barriers, any function affecting the attributes object (including destruction) does not affect any previously initialized barrier.
RETURN VALUES
Upon successful completion, the pthread_barrierattr_destroy() and pthread_barrierattr_init() functions returns 0. Otherwise, an error num- ber is returned to indicate the error.
ERRORS
The pthread_barrierattr_init() function will fail if: ENOMEM Insufficient memory exists to initialize the barrier attributes object. The pthread_barrierattr_destroy() function may fail if: EINVAL The value specified by attr is invalid.
