I tried to look up (non-MSDN) documentation for setvbuf, and I can't find anything that would indicate that _IOLBF with a size of zero would do anything other than _IONBF (line buffering with a buffer size of zero seems like not buffering, no?)
If you want the default buffers size, why not use BUFSIZ? That seems like it would achieve actual line buffering, using the default buffer. -Fab Smith, Stan wrote on Mon, 23 May 2011 at 11:58:05 > Hello, > What is the logic behind a buffer size of 1024? > Since this is shared code (Linux & Windows) the change should be identified > as Windows specific; as in > > #ifdef __WIN__ > setvbuf(stdout, NULL, _IOLBF, 1024); > #else > /* force stdout to be line-buffered */ > setvbuf(stdout, NULL, _IOLBF, 0); > #endif > >> -----Original Message----- From: [email protected] >> [mailto:ofw- [email protected]] On Behalf Of Alex >> Naslednikov Sent: Sunday, May 22, 2011 4:43 AM To: >> [email protected] Cc: Galina Tcharny; OpenSM Subject: [ofw] >> [patch][opensm] Fix for win8 assert >> >> [opensm] fix win8 assert (2<=size<=INT_MAX): setvbuf size param change >> from 0 to 1024 Signed-off by: Galina Tcharny (galina at mellanox.co.il) >> Index: B:/users/xalex/MLNX_VPI_trunk/ulp/opensm/user/opensm/main.c >> ========================================================= ========== >> --- B:/users/xalex/MLNX_VPI_trunk/ulp/opensm/user/opensm/main.c >> (revision 8023) +++ >> B:/users/xalex/MLNX_VPI_trunk/ulp/opensm/user/opensm/main.c (revision >> 8024) @@ -692,7 +692,7 @@ }; >> >> /* force stdout to be line-buffered */ >> - setvbuf(stdout, NULL, _IOLBF, 0); >> + setvbuf(stdout, NULL, _IOLBF, 1024); >> >> /* Make sure that the opensm and complib were compiled using >> same modes (debug/free) */ >> >> Alexander (XaleX) Naslednikov >> SW Networking Team >> Mellanox Technologies >> >> >> _______________________________________________ >> ofw mailing list >> [email protected] >> http://lists.openfabrics.org/cgi-bin/mailman/listinfo/ofw > _______________________________________________ > ofw mailing list > [email protected] > http://lists.openfabrics.org/cgi-bin/mailman/listinfo/ofw _______________________________________________ ofw mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/ofw
