各位大哥帮忙翻译一下int Encode(const char* pSrc, unsigned char* pDst, int nSrcLength)
{
int nSrc;
int nDst;
int nChar;
unsigned char nLeft;
nSrc = 0;
nDst = 0;
while(nSrc<nSrcLength)
{
nChar = nSrc & 7;
if(nChar == 0)
{
nLeft = *pSrc;
}
else
{
*pDst = (*pSrc << (8-nChar)) | nLeft;
nLeft = *pSrc >> nChar;
nDst++;
}
pSrc++; nSrc++;
}
return nDst;
}
int Decode(const unsigned char* pSrc, char* pDst, int nSrcLength)
{
int nSrc;
int nDst;
int nByte;
unsigned char nLeft;
nSrc = 0;
nDst = 0;
nByte = 0;
nLeft = 0;
while(nSrc<nSrcLength)
{
*pDst = ((*pSrc << nByte) | nLeft) & 0x7f;
nLeft = *pSrc >> (7-nByte);
pDst++;
nDst++;
nByte++;
if(nByte == 7)
{
*pDst = nLeft;
pDst++;
nDst++;
nByte = 0;
nLeft = 0;
}
pSrc++;
nSrc++;
}
*pDst = 0;
return nDst;
}
{
int nSrc;
int nDst;
int nChar;
unsigned char nLeft;
nSrc = 0;
nDst = 0;
while(nSrc<nSrcLength)
{
nChar = nSrc & 7;
if(nChar == 0)
{
nLeft = *pSrc;
}
else
{

nLeft = *pSrc >> nChar;
nDst++;

pSrc++; nSrc++;

return nDst;
