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
tcsetpgrp - set foreground process group ID
SYNOPSIS
#include <sys/types.h> #include <unistd.h> int tcsetpgrp(int fildes, pid_t pgid_id);
DESCRIPTION
If the process has a controlling terminal, tcsetpgrp() will set the foreground process group ID associated with the terminal to pgid_id. The file associated with fildes must be the controlling terminal of the calling process and the controlling terminal must be currently associated with the session of the calling process. The value of pgid_id must match a process group ID of a process in the same session as the calling process.
RETURN VALUES
Upon successful completion, 0 is returned. Otherwise, -1 is returned and errno is set to indicate the error.
ERRORS
The tcsetpgrp() function will fail if: EBADF The fildes argument is not a valid file descriptor. EINVAL This implementation does not support the value in the pgid_id argument. ENOTTY The calling process does not have a controlling terminal, or the file is not the controlling terminal, or the controlling termi- nal is no longer associated with the session of the calling process. EIO The process is not ignoring or holding SIGTTOU and is a member of an orphaned process group. EPERM The value of pgid_id does not match the process group ID of a process in the same session as the calling process.
