Is contiguous memory storage in a vector a recent thing or is it only
in more recent versions of C++? Ie is the following always guaranteed to
work no matter how old the compiler:

vector<u_char> mydata;
:
fill vector
:
write(fd,&mydata[0],mydata.size());

or 

write(fd,mydata.data(),mydata.size());
