skeletal 'dynamic array of strings' function - tweak needed

[fundamental]

Hello, I am trying to use a function to add strings to a 'dynamic array of strings' and wondered if someone might help me fnish this skeletal piece of code.
The function fill_array_x() works, the function fill_array_y() crashes where indicated. I'm looking for a simple fix here - hopefully a missing * or & will wrap it up. Later I will look at using structs, etc. All constructive advice welcome.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
char *names[] = { "one", "two"};
char **my_str_array = NULL;
/*-------------------------------------*/
int fill_array_x() /* this works for the global string */
{
    if (!(my_str_array = malloc(( 2 * sizeof(char*)))))  return(-1);
 my_str_array[0] = names[0];
 my_str_array[1] = names[1];
    return 0;
}
/*-------------------------------------*/
int fill_array_y(char ***str_array) /* this generic function has issues */
{
    if (!(*str_array = malloc(( 2 * sizeof(char*)))))  return(-1);
 *str_array[0] = names[0];
 *str_array[1] = names[1]; /*crashes here*/
    return 0;
}
/*-------------------------------------*/
int main()
{
 int i;

/* if (fill_array_x(my_str_array) !=0) return 9; */ /* works */
   if (fill_array_y(&my_str_array) !=0) return 9;   /* does not work*/

 for (i = 0; i < 2; i++)
     printf( "'%s'\n", my_str_array[i]);

 free(my_str_array);
 return 0;
}

*str_array[0] = names[0];
*str_array[1] = names[1]; /*crashes here*/

These you need to write as
(*str_array)[0] = names[0];
(*str_array)[1] = names[1];

*str_array[0] = names[0];
*str_array[1] = names[1]; /*crashes here*/

These you need to write as
(*str_array)[0] = names[0];
(*str_array)[1] = names[1];

That did it. Thanks for the fast and clear reply!
