but IBM JDK, which came with my WebSphere, does not handle it right:

File dir = new File( dirName );

我倒是找到了一个法子
首先列出目录下的文件和子目录，文件直接下载，子目录调用本函数（递归）
但是下载下来的文件大小不对，大侠能帮忙看看么

你要知道是用的什么版本的库（是不是有debug symbols, 32bit or 64 bit, etc) 一
定要链接到正确的版本然后你自己的编译也使用同样的设置才行
然后需要把full/dirname/that/contains/the/lib/file 加入到环境变量路径里或者把
库文件放到你的要运行程序相同的路径下。
看来楼主估计基本的gcc都不太会用还是先编译运行一个简单的helloworld和知道创建
和链接库文件再说吧 |

libname dir &dirnam;
libname dirx xport &trnnam;

发帖数: 389 | 21 假如common_base_string = "/commonbase/dirname"
我想用宏给每个进程生成一个自己的 own_base_string = commmon_base_string_
xxxxxx, xxxxxx是根据 pthread_self()拿到的 pthread_it_t.
用的时间就是直接调用 GENERATE_OWN_BASE_STRING 宏。
{
char* own_base_string;
pthread_it_t pid=pthread_self();
own_base_string= GENERATE_OWN_BASE_STRING(pid);
}
请问如何写这个宏啊？
我用 # 和##， 但是都是直接输出 pid，而不是先evaluate pid的值，在传给宏。
非常感谢。 |

To check your quota, type:
quota -v yourusername
To check the system disk usage, type:
du -k dirname
(let's say your home directory is /home/grad/username, you should try:
du -k /home/grad)
From the information you provided, there are two possbilities:
1. You are over quota
2. There are not enough disk space under the system, such as /home/grad
Probably it's because of the first reason, it's very easy to use more than
30M for a grad student, I use 180M, and many other students |

Thanks! 进一步，我想对一个目录及其子目录下的所有文件都进行同一种操作，
比如chmod 700 filename。我想用一个for循环实现。这个for循环在bash下面
怎么实现? Is it
for file in dirname;
chmod 700 file;
done
好象不太对。 |

# put all files in the hashes according to their filenames
push @dirlist,$dirname;
