/*** stdio20.h - linker I/O package
|
|
*
|
|
* Copyright <C> 1985, Microsoft Corporation
|
|
*
|
|
* Purpose:
|
|
* This is optimized stdio package for linker. Advantages over standard
|
|
* C run-time stdio are:
|
|
* - smaller size
|
|
* - greater speed
|
|
* This package is not general nature and is tailored to linker
|
|
* requrements.
