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.

TTYNAME(3)						   BSD Library Functions Manual 						TTYNAME(3)

ttyname, ttyname_r, isatty -- get name of associated terminal (tty) from file descriptor
Standard C Library (libc, -lc)
#include <unistd.h> char * ttyname(int fd); int ttyname_r(int fd, char *buf, size_t len); int isatty(int fd);
These functions operate on file descriptors for terminal type devices. The isatty() function determines if the file descriptor fd refers to a valid terminal type device. The ttyname() function gets the related device name of a file descriptor for which isatty() is true. The ttyname() function returns the name stored in a static buffer which will be overwritten on subsequent calls. The ttyname_r() function takes a buffer and length as arguments to avoid this problem.
The isatty() function returns 1 if fd refers to a terminal type device; otherwise, it returns 0 and may set errno to indicate the error. The ttyname() function returns the null terminated name if the device is found and isatty() is true; otherwise a NULL pointer is returned. The ttyname_r() function returns 0 if successful. Otherwise an error number is returned.
These functions may fail if: [EBADF] The fd argument is not a valid file descriptor. [ENOTTY] The file associated with fd is not a terminal. Additionally, ttyname_r() may fail if: [ERANGE] The bufsize argument is smaller than the length of the string to be returned.
fdevname(3), ptsname(3), tcgetattr(3), tty(4)
The isatty() and ttyname() functions appeared in Version 7 AT&T UNIX. The ttyname_r() function appeared in FreeBSD 6.0.
