分割错误打开文件

我只是想学习C http://fromlearncodethehardway.com开始。不过，我在尝试对其中一个示例进行编码时遇到了分段错误。指向我的源代码的链接。我尝试使用valgrind进一步帮助调试，但我似乎无法弄清楚这个问题。这是来自valgrind的堆栈跟踪。分割错误打开文件

调试的任何帮助将是伟大的。谢谢！

尝试将您的问题减少到更小的测试用例，并在此处包含您的代码。 – 2012-04-19 17:41:29

在Stack Overflow上使用Pastebin绝对是一个新手错误。 – chrisaycock 2012-04-19 17:41:47

在您的代码中，您有fopen调用为fopen(filename,'w'); & fopen(filename,'r+');。那些应该是fopen(filename,"w"); & fopen(filename,"r+");。第二个参数fopen应该是const char *
希望这有助于！

顺便说一下，我认为你的意思是http://c.learncodethehardway.org/
你给的地址没有解决。
