strdup() "need source"

[Matt Landau]

Not that it's any big deal, and not that we won't have 250 different
people each posting his or her own pet version of strdup to comp.lang.c,
but here's a minimalist version:

    /* strdup():  Return a copy of the argument string. */

    char *strdup(s)
    char *s;
    {
	extern char *malloc(), *strcpy();
	char *p;

	if (s && (p = malloc(strlen(s) + 1)))
	    return (strcpy(p, s));
	return (NULL);
    }

Although one can get even more minimalist with

    return (s && (p = malloc(strlen(s) + 1))) ? strcpy(p, s) : NULL;

:-)
