typedef struct Tag_Result {
char content[CHARNUM_MAX];
char type[CHARNUM_MAX];
}Result;

bool test(char* FileName,Result &testResult,float &a,float b)

testResult是一个输出参数
&testResult是一个内存地址,这个在DELPHI中怎么定义??????????

type
Tag_Result=record
content:array[0..CHARNUM_MAX-1]of Char;
type:array[0..CHARNUM_MAX-1]of Char;
end;

function test(FileNameChar
var testResult:Tag_Result
var a:single
b: single):Boolean
stdcall;

输出参数用var修饰一下就可以了。float对应Single还是Double，你查一下帮助吧。
