MAX(3)                  Library Functions Manual                  MAX(3)

NAME         top

       MAX, MIN - maximum or minimum of two values

LIBRARY         top

       Standard C library (libc, -lc)

SYNOPSIS         top

       #include <sys/param.h>

       MAX(a, b);
       MIN(a, b);

DESCRIPTION         top

       These macros return the maximum or minimum of a and b.

RETURN VALUE         top

       These macros return the value of one of their arguments, possibly
       converted to a different type (see BUGS).

ERRORS         top

       These macros may raise the "invalid" floating-point exception
       when any of the arguments is NaN.

STANDARDS         top

       GNU, BSD.

NOTES         top

       If either of the arguments is of a floating-point type, you might
       prefer to use fmax(3) or fmin(3), which can handle NaN.

       The arguments may be evaluated more than once, or not at all.

       Some UNIX systems might provide these macros in a different
       header, or not at all.

BUGS         top

       Due to the usual arithmetic conversions, the result of these
       macros may be very different from either of the arguments.  To
       avoid this, ensure that both arguments have the same type.

EXAMPLES         top

       #include <stdio.h>
       #include <stdlib.h>
       #include <sys/param.h>

       int
       main(int argc, char *argv[])
       {
           int a, b, x;

           if (argc != 3) {
               fprintf(stderr, "Usage: %s <num> <num>\n", argv[0]);
               exit(EXIT_FAILURE);
           }

           a = atoi(argv[1]);
           b = atoi(argv[2]);
           x = MAX(a, b);
           printf("MAX(%d, %d) is %d\n", a, b, x);

           exit(EXIT_SUCCESS);
       }
