列出一个目录中所有文件的名字,相当于在Linux/Unix终端命令行模式下键入ls命令的功能实现:
#include "apue.h" #include <dirent.h> int main(int argc, char *argv[]) { DIR *dp; struct dirent *dirp; if(argc != 2) err_quit("usage: ls dictionary_name"); if((dp = opendir(argv[1])) == NULL) err_sys("can't open %s", argv[1]); while((dirp = readdir(dp)) != NULL) printf("%s\n", dirp->d_name); closedir(dp); exit(0); }
