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.

pthread_attr_getscope(3C)				   Standard C Library Functions 				 pthread_attr_getscope(3C)

NAME
pthread_attr_getscope, pthread_attr_setscope - get or set contentionscope attribute
SYNOPSIS
cc -mt [ flag... ] file... -lpthread [ library... ] #include <pthread.h> int pthread_attr_getscope(const pthread_attr_t *restrict attr, int *restrict contentionscope); int pthread_attr_setscope(pthread_attr_t *attr, int contentionscope);
DESCRIPTION
The pthread_attr_setscope() and pthread_attr_getscope() functions are used to set and get the contentionscope attribute in the attr object. The contentionscope attribute can have the value PTHREAD_SCOPE_SYSTEM, signifying system scheduling contention scope, or PTHREAD_SCOPE_PROCESS, signifying process scheduling contention scope. The symbols PTHREAD_SCOPE_SYSTEM and PTHREAD_SCOPE_PROCESS are defined by the header <pthread.h>.
RETURN VALUES
If successful, the pthread_attr_setscope() and pthread_attr_getscope() functions return 0. Otherwise, an error number is returned to indi- cate the error.
ERRORS
The pthread_attr_setscope(), or pthread_attr_getscope(), function may fail if: EINVAL attr or contentionscope is invalid.
USAGE
After these attributes have been set, a thread can be created with the specified attributes using pthread_create(). Using these routines does not affect the current running thread.
