re PR libstdc++/11722 ([3.4 only] Unbuffered filebuf::sgetn is slow)
2004-09-13 Paolo Carlini <pcarlini@suse.de>
PR libstdc++/11722
* include/std/std_fstream.h (xsgetn): Declare only.
* include/bits/fstream.tcc (xsgetn): Define, optimize for the
always_noconv() case: when __n > __buflen, copy the available
buffer and issue a direct read.
* testsuite/performance/27_io/filebuf_sgetn_unbuf.cc: New.
* include/bits/fstream.tcc (xsputn): Minor tweak, reorder a
conditional.
