printf() Tricks - C - Win/GNU

It may be old-fashioned, but I still find printf (and sprintf and _vsnprintf) incredibly useful, both for printing debug output and for generating formatted strings.

Here are a few lesser-known formats that I use again and again.

Evil C

This is a collection of strange C (and some Java) constructs. It's probably best not to use them, but you should know why they work.

Calling C Code from Java

**Using native code with Java applications and the Sun JDK

Introduction

This article shows how to access C code (also called native code) from within Java code. The C code exists as a PowerPC shared library containing several Process Manager calls. The functions in the shared library are used to get and store process information. A Java front-end calls the shared library at specified intervals to retrieve and display the process information. Timing for these calls is accomplished using a thread. The front-end also includes a preferences dialog with a pseudo-custom control written in Java. This program runs as a Java application, not an applet.
