试试下面的代码,我是在redhat上编译运行的。
//g++ -o read_dir read_dir.cpp
//用于列出参数目录下的文件
#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <dirent.h>
int main(int argc, char*argv[])
{
DIR *dp;
struct dirent *dirp;
if(argc != 2)
{
printf("not enough arguments! exit!\n");
exit(0);
}
if((dp =opendir(argv[1]))== NULL)
{
printf("can't open %s!\n",argv[1]);
exit(0);
}
while((dirp = readdir(dp))!=NULL)
printf("%s\n",dirp->d_name);
closedir(dp);
}
//g++ -o read_dir read_dir.cpp

int main(int argc, char*argv[])

printf("can't open %s!\n",argv[1]);
exit(0);
}
while((dirp = readdir(dp))!=NULL)
printf("%s\n",dirp->d_name);
closedir(dp);
}
