Pk., MD 20742 Lines: 24 Message-ID: <5ajbbc$brm@yangtze.cs.umd.edu> NNTP-Posting-Host: yangtze.cs.umd.edu NNTP-Posting-User: fwmiller Xref: euryale.cc.adfa.oz.au comp.unix.bsd.misc:1873 Hello again, I've been generating all sorts of nice timing data using the timestamp counter. I've been trying to get the output to go to a file. A simple redirection, something like this, would be nice: yangtze% <program that generates data in the kernel> > <data file> Currently, I'm using uprintf() in the sections of the kernel I have instrumented to send the data to the controlling terminal. The trouble is, I'd like to be able to redirect this to a file so I can reduce the data later. uprintf() doesnt seem to work for this and printf() sends stuff only to the console. This seems like it should be simple. Thanks in advance! Later, FM -- Frank W.
