printing of every character -- 1.7 times, and, as a result, e.g.,
printing of a string of length 50 -- 2.2 times.

* include/stream.hxx (class Cyg_OutputStream): New ABC.
(class Cyg_StdioStream): inherit from Cyg_OutputStream; make
the destructor, write(), and get_error() virtual.

* src/output/vfnprintf.cxx (vfnprintf): Use ABC Cyg_OutputStream
instead of Cyg_StdioStream.

* src/common/vsnprintf.cxx (class Cyg_VsnprintfStream): New class
that specializes Cyg_OutputStream for output to a string.
(vsnprintf): Use Cyg_VsnprintfStream for printing to a string.]]> asl Sat, 27 Jan 2007 13:53:37 +0000 https://hg.ecoscentric.com/nand-ecoscentric/log/543067294b88/packages/language/c/libc/stdio/current/src/common/stream.cxx reads from I/O system so it's updated by the correct number of

stuff read from the file left in the buffer so the file positions
are inconsistent.]]> jlarmour Tue, 26 Sep 2006 18:51:22 +0000 https://hg.ecoscentric.com/nand-ecoscentric/log/91de0c0f9954/packages/language/c/libc/stdio/current/src/common/stream.cxx when configured by CDL to be unbuffered.]]> jlarmour Thu, 14 Apr 2005 16:42:12 +0000 https://hg.ecoscentric.com/nand-ecoscentric/log/fc3e63dcb859/packages/language/c/libc/stdio/current/src/common/stream.cxx jlarmour Mon, 16 Aug 2004 14:38:42 +0000 https://hg.ecoscentric.com/nand-ecoscentric/log/71a39e52b020/packages/language/c/libc/stdio/current/src/common/stream.cxx unbuffered reads.
