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
memmove - copy memory area
SYNOPSIS
#include <string.h> void *memmove(void *dest, const void *src, size_t n);
DESCRIPTION
The memmove() function copies n bytes from memory area src to memory area dest. The memory areas may overlap: copying takes place as though the bytes in src are first copied into a temporary array that does not overlap src or dest, and the bytes are then copied from the temporary array to dest.
RETURN VALUE
The memmove() function returns a pointer to dest.
