Could we please, please avoid using fixed-sized buffers, no matter
how big the buffer is? I just spent the last 3 hrs tracking down
char buff[4096]
in cmSystemTools::cmCopyFile.
Is there any reason why this function couldn't be implemented using
iterators? For example:
void cmSystemTools::cmCopyFile(const char* source,
const char* destination)
{
std::ifstream fin(source);
std::ofstream fout(destination);
std::copy( std::istream_iterator<char>(fin), std::istream_iterator<char>(), std::ostream_iterator<char>(fout) );
}
Amitha.
