    2. The second argument ("sz") is the +** size of each lookaside buffer slot. Lookaside is disabled if "sz" +** is less than 8. The "sz" argument should be a multiple of 8 less than +** 65536. If "sz" does not meet this constraint, it is reduced in size until +** it does. +**

    3. The third argument ("cnt") is the number of slots. Lookaside is disabled +** if "cnt"is less than 1. The "cnt" value will be reduced, if necessary, so +** that the product of "sz" and "cnt" does not exceed 2,147,418,112. The "cnt" +** parameter is usually chosen so that the product of "sz" and "cnt" is less +** than 1,000,000. +**

    +**

    +** [SQLITE_BUSY]. +** If the "buf" argument is NULL and an attempt +** to allocate memory based on "sz" and "cnt" fails, then +** lookaside is silently disabled. +**

    +** The [SQLITE_CONFIG_LOOKASIDE] configuration option can be used to set the +** default lookaside configuration at initialization. The +** [-DSQLITE_DEFAULT_LOOKASIDE] option can be used to set the default lookaside +** configuration at compile-time.
