可以用memcpy。memcpy Copies characters between buffers. Routine Required Header memcpy <memory.h> or <string.h> void *memcpy( void *dest, const void *src, size_t count ); Parameters dest New buffer src Buffer to copy from count Number of characters to copy LibrariesAll versions of the C run-time libraries.Return Valuesmemcpy returns the value of dest.ResThe memcpy function copies count bytes of src to dest. If the source and destination overlap, this function does not ensure that the original source bytes in the overlapping region are copied before being overwritten. Use memmove to handle overlapping regions.
自己比较就可以了... pDataBuffer = new BYTE[DataBufOffset]; pDataBufferA = new BYTE[DataBufOffset]; for(long i=0;i<DataBufOffset;i++) { if(pDataBuffer[i] != pDataBufferA[i])//这里肯定就是不同了 ;//做相应处理,break } ....
不好意思,楼主,刚才csdn提交时,一直未成功,贴错了。如果只是比较,可用, Compare characters in two buffers. int memcmp( const void *buf1, const void *buf2, size_t count );从什么地方开始不同 可用楼上newplayer1(琴剑江湖)的方法处理,应该是最简单的了。
static void PASCAL CompactDatabase( LPCTSTR lpszSrcName, LPCTSTR lpszDestName, LPCTSTR lpszLocale = dbLangGeneral, int nOptions = 0 );
throw( CDaoException, CMemoryException );???是不是这个意思

src
Buffer to copy from
count
Number of characters to copy
