// A scaling function for approximating the maximum required buffer size
// for native Enumeration calls. This value should preferably be 3, because
// at least a factor of 2 is required to convert all 16-bit client words to
// 32-bit native dwords, while character arrays require a factor of more
// than two, to account for Unicode conversion plus a four-byte pointer
// to the converted string.
//
// To specify a minimum value for the buffer size, specify the scaling
// function in form min + s, where min is the minimum and s is the scale.
// DO NOT USE PARENTHESES IN THIS EXPRESSION.
