// Functions: About fifty Win32 function wrappers
//
// Notes: 'sz' is used instead of the "correct" hungarian 'psz'
// throughout to enhance readability.
//
// Not all of every Win32 function is wrapped here. Some
// obscurely-documented features may not be handled correctly
// in these wrappers. Caller beware.

// These are privately exported for use by the Shell.

// History: 28-Dec-93 ErikGav Created
// 06-14-94 KentCe Various Chicago build fixes.
// 21-Dec-94 BruceMa Use olewcstombs + other fixes
