ISET(3)			     C Programmer's Manual		       ISET(3)

NAME
       iset_create,    iset_destroy,   iset_copy,   iset_is_empty,   iset_add,
       iset_add_range, iset_remove, iset_remove_range,	iset_clear,  iset_con-
       tains,  iset_union, iset_diff, iset_isect, iset_range, iset_nth_range -
       manipulate sets of integers

SYNOPSIS
       #include	<publib.h>

       Iset *iset_create(void);
       void iset_destroy(Iset *is);
       Iset *iset_copy(const Iset *is);

       int iset_is_empty(const Iset *is);
       int iset_add(Iset *is, long number);
       int iset_add_range(Iset *is, long number1, long number2);
       int iset_remove(Iset *is, long number);
       int iset_remove_range(Iset *is, long number1, long number2);
       void iset_clear(Iset *is);
       int iset_contains(const Iset *is, long number);
       int iset_union(Iset *is1, const Iset *is2);
       int iset_diff(Iset *is1,	const Iset *is2);
       int iset_isect(Iset *is1, const Iset *is2);
       void iset_range(const Iset *is, long *lowest, long *highest);
       int iset_nth_range(const	Iset *is, long n, long *lo, long *hi);

DESCRIPTION
       These functions operate on sets of integers (of type long).  You	clever
       people  will  know how to use them without my help, which saves me from
       writing a manual	page.
