jtc 33849ebec9 Add the asf command for absolute tape positioning. 
Some cleanup of the remote tape interface, but a lot more is needed.
Ideally, we'd have a "rmt" library which provides a remote tape API
including open, read, write, close, and ioctl.  This is useful not
only for mt, but also for programs like tar, cpio, pax, backup and
restore.

christos beb57fb35d - Add function callback capability when variables are set. 
- Add setvarsafe that returns an error instead of longjmp() to the
  error code.
 1996-06-25 16:49:05 +00:00
christos cc31700a92 - Add getoptsreset to be used as a callback function when OPTIND is set. 
This is used to implement the POSIX behavior when OPTIND=1
- Call setvarsafe instead of setvar. If one ran
	"getopts optstr badvariable"
  where badvariable contained an illegal variable name, there was no way
  to recover, since setvar() would longjmp on the error.

christos 70ad20e9f1 Include header files to get function prototypes; don't use home grown ones. 1996-06-25 16:40:06 +00:00
christos 0bc88b2434 getopts fixes: 
1. OPTIND value was not computed correctly when the argument was part of the
   option string (i.e. for "l:" "-l 1" was working "-l1" was not). (PR/2505).
2. OPTARG was not being unset in case of errors [in the non POSIX error case].
3. optvar could be set to random values.
4. Option string starting with a : was not treated specially as POSIX
   specifies (if the option string starts with a :, then there is no
   error printed when there are missing option arguments or illegal options,
   and OPTARG and optvar are being set specially).
5. Implemented getopts "opts" optvar [arg]. The optional argument case
   was not implemented.

To do:
- what does Posix say about resetting the getopts state? Bash does it
  by setting OPTIND=0; is that correct? Should we be doing the same thing?
- should we be using getopt(3) for everything internal to the shell? Is that
  feasible because we might need to handle multiple invocations at once.
