function MySend(S: TSocket; var Buf; len, flags: Integer): Integer; stdcall; 請問 Buf 是宣告何種的變數呢?

我不清楚delphi中的Buf是什麼，但是我在C 的winsock中看到類似的function，裡面的buf是定義成char

hi,依照Delphi online help的說明,這個稱為"Untyped parameters",即你可以傳任何型態的參數進去. 不過,即使是任何型態都可以傳,但被呼叫的程式裡仍然會需要對傳入的參數做檢查 底下是online help的說明 You can omit type specifications when declaring var, const, and out parameters. (Value parameters must be typed.) For example, procedure TakeAnything(const C); declares a procedure called TakeAnything that accepts a parameter of any type. When you call such a routine, you cannot pass it a numeral or untyped numeric constant. Within a procedure or function body, untyped parameters are incompatible with every type. To operate on an untyped parameter, you must cast it. In general, the compiler cannot verify that operations on untyped parameters are valid.

了解，謝謝了 我使 用 char(Buf) 編繹就過了

引言: function MySend(S: TSocket; var Buf; len, flags: Integer): Integer; stdcall; 請問 Buf 是宣告何種的變數呢?

在 var Buf 下，若我想要 B2:array of pchar; 要怎麼讓 Buf => 放到B2的陣列呢
