reinitialize a global variable array from within a function

How would I do this? I want the value of the variable to be returned to its initial value of: char x[MAX_DIR_LENGTH]={0x0};

I've tried

Code:

---

x[MAX_DIR_LENGTH]='\0';
x[MAX_DIR_LENGTH]={0x0};

---

Code:

---

memset( x, '\0', MAX_DIR_LENGTH );

---

does the same as your initialisation.

Or even just a regular for loop, which doesn't have the problem of figuring out the size of each element of the array.

memset( x, '\0', MAX_DIR_LENGTH * sizeof *x );
Will at least save embarrasment if your array isn't an array of chars

For example, using memset to clear arrays of pointers and floats is non-portable.
