C语言中的一跳命令转Delphi语法。(200分)

typedef void (FAR WINAPI *DOWNLOADMSGPROC)(LPTSTR str,BOOL newline);<br><br>This function type is used by some program downloading procedures to offer the option of reporting a status message.<br><br>Arguments<br><br>str Message string.<br>newline Indicates if a new line should be added by the called procedure.<br><br>Return Value<br><br>None.<br>请教高手，如何把typedef void (FAR WINAPI *DOWNLOADMSGPROC)(LPTSTR str,BOOL newline);写成Delphi语法。先谢了。

procedure(str : pchar; newline : boolean) of object;

type<br> &nbsp;TDownloadMsgProc = procedure(str: PChar; NewLine: Boolean); stdcall;<br><br>函数指针，楼上写的是什么？

那么：<br>typedef long &nbsp;(FAR WINAPI *DOWNLOADGETPROC)(long nIndex,LPTSTR lpszBuffer,long nMaxLength);<br>是不是＝<br>type<br> &nbsp;TDownloadGetProc = Function(nIndex: Int64; lpszBuffer: PChar;nMaxLength:Int64):int64; stdcall;<br>谢谢errorcode <br>还有：<br>long &nbsp;PmacDownloadA(DWORD dwDevice, DOWNLOADMSGPROC msgp, DOWNLOADGETPROC getp, DOWNLOADPROGRESS pprg, PCHAR filename, BOOL macro, BOOL map, BOOL log, BOOL dnld);<br><br>This function takes an ASCII file, processes it, and downloads it from the PC to the PMAC. &nbsp;Processing includes MACRO parsing and compiling PLCs, for example. &nbsp;This function can generate several residual files, as described in the table below. ....<br>我已经改为Delphi语法：<br> &nbsp; function &nbsp; PmacDownloadA(dwDeviceWORD;msgpOWNLOADMSGPROC;getp: DOWNLOADGETPROC; pprgOWNLOADPROGRESS; filenameCHAR; macro,map,log,dnld:boolean):Int64;stdcall;external 'PComm32.dll';<br><br>请问errorcode大侠：在调用PmacDownloadA函数时，参数表中的msgp，getp，pprg用什么方式的数据项，谢谢。

Delphi就几个类型函数指针，of object是Delphi的事件指针，一般我们写的onFormCreate之类的。还有就是Windows的，一般就是用于回调函数。<br><br>函数指针就是你再写一个函数，将函数名称传递给那个调用者，如：<br>function MyDownloadProc(Index: DWORD; buf: PChar; len: DWORD): DWORD; stdcall;<br>begin<br> &nbsp;Result := 0;<br> &nbsp;....<br>end;<br><br>abcCallFunc(@MyDownloadProc, ....);<br><br>另：long=&gt;DWORD, Cardinal<br><br>不多说了，这些是一些基础知识，很容易找到的。

虽然没有完全明白,还是谢谢errorcode大侠
