strverscmp("gliv-1.0", "gliv-1.0.1") => -46 => Good
strverscmp("gliv-1.0.tar.gz", "gliv-1.0.1.tar.gz") => 67 => Bad
Given that strverscmp is mainly used to sort filenames of versionned projects,
it should apply the same order with or without a suffix.

You are looking for a function like rpmvercmp in <rpm/rpmlib.h> which provides segmented comparison. But why should that be in libc? -- What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |WAITING http://sourceware.org/bugzilla/show_bug.cgi?id=3506 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ^ permalink raw reply [flat|nested] 4+ messages in thread
