delphi 调用 vc dll 问题
我调用vc的dll，传送结构体参数。vc接受后从内存中拷贝出我传送的值。转换之后是乱码
结构体怎么定义的?
//向终端发送门禁报警信息
function alarmSentDoor(var pDoorPara :Alley_ALARM_PARA):boolean;stdcall;external 'warnerdll.dll';
结构体定义
Door_ALARM_PARA = record
cAlarmTime : array[0..MAX_ALARM_TIME_LEN] of char; //报警时间
cDoorID : array[0..MAX_ALLEY_ID_LEN] of char; //报警门号
cCause : array[0..MAX_ALARM_CAUSE_LEN] of char; //报警原因
end;
