C++ 代码改java代码--急急！！

typedef struct

{

BYTE baOrigMDN[8]; /* 主叫用户MDN */

BYTE baDestMDN[8]; /* 被叫用户MDN */

BYTE bOrigIsVIP; /* 对SP无用*/

BYTE bMsgIsSeed; /* 短消息是否种子 */

BYTE baSeedID[6]; /* 种子短信ID */

BYTE baQijiSeedID[6]; /* 种子短信ID标示 */

}csrMTSMsgStrc_T;

如何将baQijiSeedID[6]的内容转成时间字符串（YYYYMMDDHHMMSS）的算法：

BYTE baTimeTmp[6] ={0};

CHAR caSubmitTime[20] = {0}; //内容为YYYYMMDDHHMMSS的时间

memcpy(baTimeTmp, baQijiSeedID, 6); //把baQijiSeedID内存区域的6个字节复制到baTimeTmp

if (0x80 == (baQijiSeedID [4] & 0xC0))

{

baTimeTmp[0] = 0;

}

if (0x20 == (baQijiSeedID [4] & 0x30))

{

baTimeTmp[1] = 0;

}

if (0x08 == (baQijiSeedID [4] & 0x0C))

{

baTimeTmp[2] = 0;

}

if (0x02 == (baQijiSeedID [4] & 0x03))

{

baTimeTmp[3] = 0;

}

csfClockDecodeProc(baTimeTmp, (BYTE *) caSubmitTime);

// 时间结构
typedef struct
{
BYTE second;
BYTE minute;
BYTE hour;
BYTE day;
BYTE month;
WORD year;
BYTE week;
BYTE Count10ms;
} ClockStruc;

/*
* FUNCTION NAME: void TIME_TO_CLOCK(TimePtr, ClockPtr)
* DESCRIPTION: relative clock to real clock
* INPUT: TimePtr: store time pointer
* ClockPtr: store clock pointer
*/
void TIME_TO_CLOCK(DWORD *TimePtr, ClockStruc *ClockPtr)
{
WORD DaysPerYear = 365;
WORD year;
DWORD days, dayss;
DWORD seconds;
BYTE month, day, week, hour, minute, second;

days = *TimePtr / 86400; //一天86400s转换为days
seconds = *TimePtr % 86400;
hour = (BYTE)(seconds / 3600);
seconds = seconds % 3600;
minute = (BYTE)(seconds / 60);
second = (BYTE)(seconds % 60);
dayss = days;

/* compute year */
year = 1994;
while (days >= DaysPerYear) // DaysPerYear = 365
{
days -= DaysPerYear;
if ((++ year % 4) == 0)
DaysPerYear = 366;
else
DaysPerYear = 365;
}

/* compute month */
if ((year % 4) == 0)
DaysPerMonth[1] = 29;
else
DaysPerMonth[1] = 28;

month = 1;
while (days >= DaysPerMonth[month - 1])
{
days -= DaysPerMonth[month - 1];
month ++;
}

/* compute date and week */
day =(BYTE)(days + 1);
week = (BYTE)((dayss + 6) % 7);
if (week == 0)
week = 7;

ClockPtr->year = year;
ClockPtr->month = month;
ClockPtr->day = day;
ClockPtr->hour = hour;
ClockPtr->minute = minute;
ClockPtr->second = second;
ClockPtr->week = week;
}

- 函数名: csfClockDecodeProc

- 功能描述: 将DWORD(4个字节)时间值转换为YYYYMMDDHHMMSS字符串

- 输入: BYTE *pTime ---->DWORD值(秒数)的版权短信发送时间

- 输出: const BYTE *pClock ----> YYYYMMDDHHMMSS字符串

-----------------------------------------------------------------------*/

void csfClockDecodeProc(const BYTE *pbTime, BYTE *pbClock)

{

ClockStruc tClockPtr = {0};

DWORD dwTime = 0 ;

BYTE i;

memcpy(&dwTime, pbTime, 4);

TIME_TO_CLOCK(&dwTime, &tClockPtr);

memset(pbClock, 0, 20);

for (i = 0; i < 4; i++) /* 年 */

{

pbClock[3 - i] = tClockPtr.year % 10 + 0x30;

tClockPtr.year = tClockPtr.year / 10;

}

pbClock[4] = tClockPtr.month / 10 + 0x30; /* 月 */

pbClock[5] = tClockPtr.month % 10 + 0x30;

pbClock[6] = tClockPtr.day / 10 + 0x30; /* 日 */

pbClock[7] = tClockPtr.day % 10 + 0x30;

pbClock[8] = tClockPtr.hour / 10 + 0x30; /* 时 */

pbClock[9] = tClockPtr.hour % 10 + 0x30;

pbClock[12] = tClockPtr.second / 10 + 0x30; /* 秒 */

}

步骤如下：1：将BCD码的高低4位互换

2：将互换后的BCD码转为字符串

A）对于种子短信ID的转码算法

/*---------------------------------------------------------------------

- 函数名: csBcdToStr

- 功能描述: 将BCD码转换成字符串

- 输入: pbBcd ----> BCD码流

- bInLen ----> BCD码流的字节数

- bBufLen ----> 接收字符串用缓冲区长度

- 输出: pcStrBuf ----> 接收字符串用缓冲区

- 返回: TRUE/FALSE

-----------------------------------------------------------------------*/

BOOL csBcdToStr( BYTE* pbBcd,

BYTE bInLen,

PCHAR pcStrBuf,

BYTE bBufLen)

{

BYTE bTmp;

BYTE cTmp;

BYTE i;

BYTE bMaxBcdLen;

if( !pbBcd || !pcStrBuf || !bBufLen ) /* 入参检查 */

{

return FALSE;

}

bMaxBcdLen = min(bInLen*2, bBufLen-1);

for( i=0; i<bMaxBcdLen; i++ )

{

bTmp = pbBcd[i/2];

if( i&1 ) /* 奇数 */

{

bTmp = bTmp >> 4;

}

bTmp &= 0x0f;

if((bTmp >= 0) && (bTmp <=9))

cTmp = bTmp +'0';

else if(bTmp == 0x0d)

cTmp = '*';

else if(bTmp == 0x0e)

cTmp = '#';

else if (bTmp == (BYTE)0x0f)

break;

else

return FALSE;

pcStrBuf[i] = cTmp;

}

pcStrBuf[i] = 0; /* 字符串结束 */

return TRUE;

}

B）对于用户MDN的转码算法

VOID csrBCDToString(const BYTE *lpBcd,CHAR *lpString,BYTE size)

{

BYTE i,j=0;

BYTE ch;

for(i=0;i<size;i++)

{

ch = (lpBcd[i]&0xF0)>>4;

if(ch<=9 /*&& ch>=0*/)

{

lpString[j] = (CHAR)(ch+0x30); //from '0'

j++;

}

else if(ch>=10 && ch<=15)

{

lpString[j] = (CHAR)(ch+0x41-10); //from 'A'

j++;

}

else // if(ch==0x0f)

{

if( j< size*2 )

{

while ( j<size*2 ) lpString[j++] = 'f';

lpString[j] = 0x00;

return ;

}

lpString[j++]=0x00;

break;

}

ch = lpBcd[i]&0x0F;

if(ch<=9 /*&& ch>=0*/)

lpString[j++]= (CHAR)(ch+0x30);

else if(ch>=10 && ch<=15)

lpString[j++] = (CHAR)(ch+0x41-10); //from A

else //if(ch==0x0f)

{

if( j< size*2 )

{

while(j<size*2) lpString[j++] = 'f';

lpString[j] = 0x00;

return ;

}

lpString[j++]=0x00;

break;

}

} // for

lpString[j++]=0x00;

return ;

}
