1.304 -// We implement basic_streambuf<char, char_traits<char> > very differently
1.305 -// than the general basic_streambuf<> template. The main reason for this
1.306 -// difference is a requirement in the C++ standard: the standard input
1.307 -// and output streams cin and cout are required by default to be synchronized
1.308 -// with the C library components stdin and stdout. This means it must be
1.309 -// possible to synchronize a basic_streambuf<char> with a C buffer.
1.310 -//
1.311 -// There are two basic ways to do that. First, the streambuf could be
1.312 -// unbuffered and delegate all buffering to stdio operations. This
1.313 -// would be correct, but slow: it would require at least one virtual
1.314 -// function call for every character. Second, the streambuf could use
1.315 -// a C stdio FILE as its buffer.
1.316 -//
1.317 -// We choose the latter option. Every streambuf has pointers to two
1.318 -// FILE objects, one for the get area and one for the put area. Ordinarily
1.319 -// it just uses a FILE object as a convenient way to package the three
1.320 -// get/put area pointers. If a basic_streambuf<char> is synchronized with
1.321 -// a stdio stream, though, then the pointers are to a FILE object that's
1.322 -// also used by the C library.
1.323 -//
1.324 -// The header <stl/_stdio_file.h> encapsulates the implementation details
1.325 -// of struct FILE. It contains low-level inline functions that convert
1.326 -// between whe FILE's internal representation and the three-pointer
