Linux 上写C++ （2）——创立目录

//创立目录

int mk_dir(char *dir)?

{

??? DIR *mydir = NULL;?

if((mydir= opendir(dir))==NULL)//判断目录

??? {?

?????????????????? if (ret != 0)?

?????????????????? {?

??????????????????????????? return -1;?

?????????????????? }?

?????????????????? printf("%s created sucess!/n", dir);?

??? }?

??? return 0;?

}

//创立所有目录

int mk_all_dir(char *dir)?

{?

??? bool flag = true;?
