刚接触,遇到这个警告,请各位高手指教,谢谢,源码如下:
library ChuShiHua;{ 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
ShareMem,
SysUtils,
windows,
Classes;
function Initial():integer;stdcall;
var buf:PChar;
begin
buf:='EB 90 82 00 00 00 00 00 00 00 00 00 00 00 00 00';
if Length(buf)=16 then
result:=0;
end;{$R *.res}
exports
Initial;begin
end.

end;{$R *.res}
exports
Initial;begin
end.
result:=0;这句if不满足的话就没有返回值了
var
buf:PChar;
begin
Result := 1;
buf:='EB 90 82 00 00 00 00 00 00 00 00 00 00 00 00 00';
if Length(buf)=16 then
result := 0;
end;或者function Initial():integer;stdcall;
var
buf:PChar;
begin
buf:='EB 90 82 00 00 00 00 00 00 00 00 00 00 00 00 00';
if Length(buf)=16 then
result := 0
else
Result := 1;
end;顺便说一句,养成良好的代码书写习惯,对人对己都很重要。
