library Project2;{ Important note about DLL memory management: ShareMem must be the
first unit in your library's USES clause AND your project's (select
Project-View Source) USES clause if your DLL exports any procedures or
functions that pass strings as parameters or function results. This
applies to all strings passed to and from your DLL--even those that
are nested in records and classes. ShareMem is the interface unit to
the BORLNDMM.DLL shared memory manager, which must be deployed along
with your DLL. To avoid using BORLNDMM.DLL, pass string information
using PChar or ShortString parameters. }uses
SysUtils,
Classes;{$R *.res}
function AddNumber(x,y:integer):integer;stdcall;
begin
result:=x+y;
end;
function MaxNum(x,y:integer):integer;stdcall;
exports
AddNumber;
MaxNum;begin
end.
有个大问题,如果把exports后面的MaxNum去掉就是一切正常啊,但是你一旦加上就出现错误了啊,也就是说这个dll只能够导出一个函数啊,这是什么原因啊!请各位高手指教!!

AddNumber,-------------注意這是用','
MaxNum;
