error: invalid cast from type _gnu_cxx::__normal_iterator<> to unsigned char*

在windows VC6编译器上，编译如下代码：

1     typedef unsigned char  BYTE;

2     vector<BYTE>    pBuffer;

3

4     BYTE RtpHeader[12] ="abcdefg1234";

5     DWORD bufferLen = 160;

6     pBuffer.reserve(bufferLen);

7     pBuffer.assign(bufferLen, 0x00);

8     memcpy(pBuffer.begin(), RtpHeader, 12);

成功，而用g++(gcc) 4.4.7版编译器没有编译成功，提示第8行

8：error: invalid cast from type 鈥榑_gnu_cxx::__normal_iterator<unsignedchar*, std::vector<unsigned char, std::allocator<unsigned char> >>鈥totype BYTE* ，可见g++编译器严格的多，将第8行作如下改动即可编译成功：

8     memcpy(&(*pBuffer.begin()), RtpHeader,12);
