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.

BN_add_word, BN_sub_word, BN_mul_word, BN_div_word, BN_mod_word - arithmetic functions on BIGNUMs with integers
#include <openssl/bn.h> int BN_add_word(BIGNUM *a, BN_ULONG w); int BN_sub_word(BIGNUM *a, BN_ULONG w); int BN_mul_word(BIGNUM *a, BN_ULONG w); BN_ULONG BN_div_word(BIGNUM *a, BN_ULONG w); BN_ULONG BN_mod_word(const BIGNUM *a, BN_ULONG w);
These functions perform arithmetic operations on BIGNUMs with unsigned integers. They are much more efficient than the normal BIGNUM arith- metic operations. BN_add_word() adds w to a ("a+=w"). BN_sub_word() subtracts w from a ("a-=w"). BN_mul_word() multiplies a and w ("a*=b"). BN_div_word() divides a by w ("a/=w") and returns the remainder. BN_mod_word() returns the remainder of a divided by w ("a%m"). For BN_div_word() and BN_mod_word(), w must not be 0.
BN_add_word(), BN_sub_word() and BN_mul_word() return 1 for success, 0 on error. The error codes can be obtained by ERR_get_error(3). BN_mod_word() and BN_div_word() return a%w.
bn(3), ERR_get_error(3), BN_add(3)
BN_add_word() and BN_mod_word() are available in all versions of SSLeay and OpenSSL. BN_div_word() was added in SSLeay 0.8, and BN_sub_word() and BN_mul_word() in SSLeay 0.9.0. 0.9.7a 2002-09-25 BN_add_word(3)
