/*
 * MtVerify.h
 *
 * Error handling for applications in
 * "Multitheading Applications in Win32"
 *
 * The function PrintError() is marked as __inline so that it can be
 * included from one or more C or C++ files without multiple definition
 * errors. For the examples in this book, this works fine.
 * To use the PrintError() in an application, it should be taken out,
 * placed in its own source file, and the "__inline" declaration removed
 * so the function will be globally available.
