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.

SEEKDIR(3)						     Linux Programmer's Manual							SEEKDIR(3)

NAME
seekdir - set the position of the next readdir() call in the directory stream.
SYNOPSIS
#include <dirent.h> void seekdir(DIR *dirp, long loc); Feature Test Macro Requirements for glibc (see feature_test_macros(7)): seekdir(): _XOPEN_SOURCE || /* Glibc since 2.19: */ _DEFAULT_SOURCE || /* Glibc versions <= 2.19: */ _BSD_SOURCE || _SVID_SOURCE
DESCRIPTION
The seekdir() function sets the location in the directory stream from which the next readdir(2) call will start. The loc argument should be a value returned by a previous call to telldir(3).
RETURN VALUE
The seekdir() function returns no value.
ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7). +----------+---------------+---------+ |Interface | Attribute | Value | +----------+---------------+---------+ |seekdir() | Thread safety | MT-Safe | +----------+---------------+---------+
CONFORMING TO
POSIX.1-2001, POSIX.1-2008, 4.3BSD.
NOTES
In glibc up to version 2.1.1, the type of the loc argument was off_t. POSIX.1-2001 specifies long, and this is the type used since glibc 2.1.2. See telldir(3) for information on why you should be careful in making any assumptions about the value in this argument.
