) -> i32
Find the table row preceding the referenced table row in a secondary quadruple-precision floating-point index table
@brief Find the table row preceding the referenced table row in a secondary quadruple-precision floating-point index table
@param iterator - The iterator to the referenced table row
@param primary - Pointer to a uint64_t
variable which will have its value set to the primary key of the previous table row
@return iterator to the table row preceding the referenced table row assuming one exists (it will return -1 if the referenced table row is the first one in the table)
@pre iterator
points to an existing table row in the table or it is the end iterator of the table
@post *primary
will be replaced with the primary key of the table row preceding the referenced table row if it exists, otherwise *primary
will be left untouched
