C语言解析ini文件

/************************************************************************ Filename : IniFile.C Version : 0.51 Author(s) : Carsten Breuer --[ Description ]------------------------------------------------------- This file contains a complete interface to read and write ini files like windows do it. It's also avaiable as a C++ class. --[ History ] ---------------------------------------------------------- 0.10: Original file by Carsten Breuer. First beta version. 0.20: Some bugs resolved and some suggestions from jim hall (freedos.org) implemented. 0.30: Some stuff for unix added. They dont know strupr. Thanks to Dieter Engelbrecht (dieter@wintop.net). 0.40: Bug at WriteString fixed. 0.50: Problem with file pointer solved 0.51: We better do smaller steps now. I have reformated to tab4. Sorry New function DeletepKey added. Thanks for the guy who post this. --[ How to compile ]---------------------------------------------------- This file was developed under DJGPP and Rhide. If you are familiar with Borland C++ 3.1, you will feel like at home ;-)). Both tools are free software.
