source: branches/2.2.2/mindi-busybox/coreutils/basename.c @ 1247

Last change on this file since 1247 was 821, checked in by Bruno Cornec, 14 years ago

Addition of busybox 1.2.1 as a mindi-busybox new package
This should avoid delivering binary files in mindi not built there (Fedora and Debian are quite serious about that)

28 *
29 * Changes:
30 * 1) Now checks for too many args.  Need at least one and at most two.
31 * 2) Don't check for options, as per SUSv3.
32 * 3) Save some space by using strcmp().  Calling strncmp() here was silly.
