}
在上面的代码,这里是我得到的运行代码时的输出:段错误读取时的命令行参数
$ ./output test.txt
Argument count is = 2
The 0th argument to the file is ./output
The current working directory is = /home/welcomeuser
File name entered is = test.txt
The complete path of the file name is = /home/welcomeusertest.txt
Segmentation fault (core dumped)
谁能请我明白为什么我得到一个核心转储错误?
也许初始化'size'会是另一个好主意。 – 2010-03-31 22:26:59
getcwd()将向malloc缓冲区传递一个空指针。 – 2010-03-31 22:28:15
@ honk: 哈哈,真的:)。 – slacker 2010-03-31 22:29:03
