关于用户提供的ftp头文件中，有一个疑惑请高手解疑

Global $__g_hWinInet_FTP = -1
DllCall($__g_hWinInet_FTP, 'bool', 'InternetCloseHandle', 'handle', $l_InternetSession)
DllCall第一个参数不是dll文件名吗，这个位置用“-1”表示是什么用途？不懂
这个文件是Include\FTPEx.au3中的内容。 回复 1# wydssx
这个头文件你一定没有看完,一般会在载入的时候运行初始化函数.然后这个变量就变成dllopen的句柄了
-1 在指针中一般代表空指针,也是用来初始化的意思 本帖最后由 wydssx 于 2016-10-19 20:19 编辑
这个文件中和这个变量关联的都看了。并没有初始化的动作。在调用ftp函数时，我向它传递相关参数，例如
Func _FTP_Open($s_Agent, $l_AccessType = $INTERNET_OPEN_TYPE_DIRECT, $s_ProxyName = '', $s_ProxyBypass = '', $l_Flags = 0)
If $__g_hWinInet_FTP = -1 Then __FTP_Init()
Local $ai_InternetOpen = DllCall($__g_hWinInet_FTP, 'handle', 'InternetOpenW', 'wstr', $s_Agent, 'dword', $l_AccessType, _
'wstr', $s_ProxyName, 'wstr', $s_ProxyBypass, 'dword', $l_Flags)
If @error Or $ai_InternetOpen = 0 Then Return SetError(-1, _WinAPI_GetLastError(), 0)
Return $ai_InternetOpen
EndFunc ;==>_FTP_Open
在调用执行到上面代码时，DllCall这个位置，按你说的是dllopen反回的句柄，整个过程都没有我要使用的dll文件名称，对于那么它是怎么知道要调用哪个ftp相关的dll文件呢。
附上真个文件的代码：

这个就是初始化的代码，在使用 FTP 函数之前，要调用 FTP_Init() 来初始化。
如果你没有初始化直接调用了 FTP_Open ，那么这个函数内部也会帮你再调用一次FTP_Init()。
仔细一点。 文件开头给 $__g_hWinInet_FTP 赋值是为了初始化一个用于判断的值， $__g_hWinInet_FTP，而真正在使用的时候会调用 FTP_Init() 来初始化的。注意加红的逻辑判断。
