xt_int_cmp(3)		   Library Functions Manual		 xt_int_cmp(3)

NAME
       xt_int_cmp() - Compare two ints for sort(3), bsearch(3),	etc.

LIBRARY
       #include	<xtend/math.h>
       -lxtend

SYNOPSIS
       int     xt_int_cmp(const	int *n1, const int *n2)

ARGUMENTS
       n1, n2  Pointers	to two int values

DESCRIPTION
       This  is	 a function that compares two ints as a	service	to polymorphic
       functions  such	as  qsort(3),  bsearch(3),  etc.    The	  address   of
       xt_int_cmp() is passed as an argument to	perform	the data type specific
       comparison on behalf of the sort	of search function.

RETURN VALUES
       A  value	> 0 if *n1 is greater than *n2 A value < 0 if *n1 is less than
       *n2 0 if	the values are equal

EXAMPLES
       int  list[LIST_SIZE];

       // sizeof(*list)	will continue to work if we change the data type
       // We'll	still need to change the cmp function, though
       qsort(list, LIST_SIZE, sizeof(*list),
	     (int (*)(const void *, const void *))xt_int_cmp);

SEE ALSO
       qsort(3), heapsort(3), mergesort(3), bsearch(3)
