What is the problem with this code. I simply can't figure out:


#include <stdio.h>
#include <string.h>

char *a(char *);
void t(char *);

/* You should call it with at least one parameters, ex:
        ./a.out test <enter>
*/

void
main(int argc, char *argv[])
{
        char *dir;

        ++argv;
        printf("%s\n", *argv);

        dir = a(*argv);
        t(dir);

        printf("%s\n", *dir);
}


void
t(char *a)
{
        while (*a)
                *a++ = '1';
}

char *
a(char *b)
{
        return strdup(b);
}
