// Module: UAPIINIT (static lib)
|
|
//
|
|
// Synopsis: This static library wraps up the initialization code needed for a module
|
|
// to use cmutoa.dll. Calling the InitUnicodeAPI function either sets up
|
|
// the modules U pointers (this library also contains all the U pointer
|
|
// declarations) with the W version of the API if running on NT or the
|
|
// appropriate A or UA API depending on whether conversion is needed before/after
|
|
// calling the windows API or not. Modules using this lib should include the
|
|
// uapi.h header in their precompiled header and should have cmutoa.dll handy
|
|
// on win9x. The idea for this library and the associated dll was borrowed
|
|
// from F. Avery Bishop's April 1999 MSJ article "Design a Single Unicode
|
|
// App that Runs on Both Windows 98 and Windows 2000"
