如下代码（支持windows与Linux）会以【16进制】【每行16字节】打印出一块内存的内容：

void PrintBuffer(void* pBuff, unsigned int nLen){    if (NULL == pBuff || 0 == nLen)    {        return;    }    const int nBytePerLine = 16;    unsigned char* p = (unsigned char*)pBuff;    char szHex[3*nBytePerLine+1] = {
   0};    printf("-----------------begin-------------------\n");    for (unsigned int i=0; i

打印出来的结果如下：
