int ReadSrvReq(char* ctrlMsg, char* subCode,
char* contentMsg, int* msgLen,
int timeOut)
DELPHI中声明：
TReadSrvReq=function(ctrlMsg:Pchar;subCode:Pchar;contentMsg:Pchar; msgLen:integer;timeOut:integer):integer;stdcall;
调用：
mw:HWND;
mt:TCSGP_ReadConf;
mt1: TReadSrvReq;
a:integer;
st:string;
p:pchar;
ctrlMsg:string;
subCode:string;
contentMsg:string;
msgLen:integer;
time1:String;
mw:=loadlibrary('CSGPAPI_DLL.dll');
if mw<>0 then
try
mt1:=GetProcaddress(mw,'ReadSrvReq');
if assigned(mt1) then
a:=mt1(@ctrlMsg,@subCode,@contentMsg, msgLen,5);
finally
FreeLibrary(mw);
end;
到了这步a:=mt1(@ctrlMsg,@subCode,@contentMsg, msgLen,5);就出错了。
请问DLL函数应怎么声明，参数怎么传呢？
