有哪位大哥知道createdirectory和createdirectoryA用法和区别么,该怎么解决

有哪位大哥知道createdirectory和createdirectoryA用法和区别么
不太会调用API函数，哪位大哥指教下……

------解决方案--------------------
type SECURITY_ATTRIBUTES from structure
ulong nLength
ulong lpSecurityDescriptor
boolean bInheritHandle
end type

FUNCTION ulong CreateDirectory(ref string lpPathName,ref 
 SECURITY_ATTRIBUTES lpSecurityAttributes) LIBRARY "kernel32.dll" ALIAS FOR "CreateDirectoryA"

它俩是一个东西!

string s_dir
SECURITY_ATTRIBUTES sa
s_dir = 'xxx'
sa.nlength = 0
...
createdricetory(s_dir,sa)


------解决方案--------------------

pb的CreateDirectory 函数可以再当前目录里建立一个子目录

string ls_path="aaa"
integer li_filenum
CreateDirectory ( ls_path )

api的CreateDirectory 建目录也是但前目录
