X.LP X.B psi_create() Xcreates an iterator. The only operation that should be applied to Xan iterator after it is created is X.B psi_start(). X.LP X.B psi_destroy() Xdestroys the iterator. X.LP X.B psi_reset() Xchanges the pset that is being iterated to X.I pset. X.LP X.B psi_start() Xstarts an iteration and returns the first pointer Xin the pointer set. X.LP X.B psi_next() Xreturns the next pointer in the set. X.LP X.B psi_remove() Xremoves the current pointer from the set. The current pointer is Xthe one returned most recently from either X.B psi_start() Xor X.B psi_next(). X.SH "RETURN VALUES" X.LP X.B psi_create() Xreturns an iterator handle on success or X.SM NULL Xon failure. X.LP X.B psi_start() Xreturns the first pointer from the set or X.SM NULL Xif the set is empty. X.LP X.B psi_next() Xreturns a pointer or X.SM NULL Xif the end of the set is reached. X.SH WARNINGS X.B psi_create() Xis the only function in this library. The rest of the interface is macros. X.LP XThis interface may be eliminated in a future release of the X.I pset Xlibrary.

It invokes the 'tester' script which does the real work. X'tester' is a Bourne shell script. However, it expects that the shell Xsupports functions and /bin/sh does not support functions on all Xoperating systems. Therefore, 'testlib' decides what shell to use to Xexecute 'tester'. On Suns, it uses /bin/sh. On DECstations, it uses X/usr/bin/ksh. The decision is made by checking the ARCH environment Xvariable. X XExercising some of the SIO functions in an automatic fashion is a Xdifficult task, so you will have to do it manually by visually Xinspecting the results of programs that exercise them. The following Xis a list of functions and programs testing them (with a description of Xthe expected behavior): X X1. Sbuftype X X PROGRAM: buftest.c X DESCRIPTION: X This program prints two groups of lines. The first group is printed X using line-buffering while the second group is printed using X full-buffering. X The first group of lines should appear one line at a time every X 3 seconds. The second group of lines should appear all lines together X after about 10 seconds. X X2. Stie, Suntie X X PROGRAM: tietest.c X DESCRIPTION: X This program ties stdin to stdout and then prompts for input. X The prompts do *not* include a NEWLINE. Since the stdout is X *line buffered* when connected to a terminal, the Stie call X is what causes the prompt to appear. X The first 2 prompts happen with tied stdin, stdout. For the X 3rd prompt, stdin is untied from stdout. This will cause X the prompt to appear *after* you type something and hit RETURN. X X X XPS. If you can make testing of these functions automatic, please send X me your code so that I can include in a future SIO distribution.
