API

其实是个很简单的常识，居然搞了我半个小时……

fgetc()的返回值是int，因为这个值除了返回拿到的字符之外，还兼作错误标志。由于fgetc()允许文件中包含任意内容，所以只好增大返回值的宽度来表达。

看来还是学的太少了。之前只是注意到内核有提供这样一个接口，等到kris来信才知道，这个接口和其他平台上都不一样-_-#

在POSIX中提到，这个API不仅可以修改输入参数，而且可以返回一个静态存储的指针，说白了，你不能指望某个平台上它是线程安全的，也不能指望它不会修改你发给它的数据……

将个性化的factory提取出来，改为使用通用的factory生成同一协议的protocol对象，并将业务逻辑对象作为factory的一个参数。这样做使得代码冗余大大降低了。

I used to think that ldap_unbind() is the opposite of ldap_bind(), however I was wrong. Pierangelo Masarati (ando at openldap) pointed out that it was actually opposite of ldap_init(). So, do NOT expect init() -> bind() -> search() -> unbind() -> bind() would success, it’s simply wrong thing. You do not need to unbind() before you do another bind().

Just make a note.

Apparantly des@ has pointed out a serious problem with my patchset, say, the inconsistency of underlying API is the root of evil(tm), and should be corrected.

Let’s go go go!

This is really insteresting one. With an “advertised” shell link, Windows Installer will automatically executed to install on demand.
