Hi List, I am one of the developers of the hercules emulator (http://www.conmicro.cx/hercules), and it seems that we have hit a problem with setvbuf in more recent cygwin versions.
We capture all standard output by means of redirecting stdout to a pipe, which is subsequently read by a logger function. (printf() to stdout, which then goes to the pipe, read() by the logger function from the pipe) We have always used setvbuf(stdout, NULL, _IOLBF, 0) to ensure that each line is read by the logger as it is written. However this has now stopped working in the current release of cygwin, adding a fflush() after every printf() bypasses the error, but at the moment setvbuf does not seem to work correctly for us. What I find somewhat odd is that this only happens when I recompile under the current cygwin. If I use an older binrary (created on backlevel cygwin) then all works fine. Has anyone experienced any similar problems with streams buffering? Thanks and regards, Jan Jaeger __________________________________ Do you Yahoo!? Yahoo!
