Here is a (far from exhaustive) test file: http://www.cs.washington.edu/homes/steve/fcheck.c - Steve _______________________________________________ Do not post admin requests to the list.

This email sent to site_archiver@lists.apple.com I was using fmtcheck(3) in some code and I noticed that it choked on any format specifier that includes positional arguments (for lack of a better term). will print "1 2" since fmtcheck() cannot tell that they consume the same arguments. It also contains a few bugs such as considering %f and %lf to be different. In fact, it doesn't even recognize %lf. This was unacceptable, so I wrote my own based (loosely) upon the fmtcheck.c used in NetBSD written by Allen Briggs in 2000. (This appears to be the same version used in Darwin.) I note in the fmtcheck(3) man page, under BUGS, it says, "The fmtcheck () function does not understand all of the conversions that printf(3) does." I'm not 100% positive yet, but I think that mine does. smime.p7s
