MAX3

Usage

#include <sys/param.h>

Library

Standard C library (libc, -lc)

Overview

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

Return value

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

Errors

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

Notes

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.

Examples

#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);
}
