My memset sets the whole string to NULL for each password we decide to generate so just subtracting from sizeof() should be the end of it right?
But as a best practice Its probably best to do it the way you have said as I'm sure my memset is eating cpu time for no reason.

BSTRING(3) Linux Programmer's Manual BSTRING(3)
NAME
bcmp, bcopy, bzero, memccpy, memchr, memcmp, memcpy, memfrob, memmem, memmove, memset - byte string operations
SYNOPSIS
#include <string.h>
int bcmp(const void *s1, const void *s2, int n);
void bcopy(const void *src, void *dest, int n);
void bzero(void *s, int n);
void *memccpy(void *dest, const void *src, int c, size_t n);
void *memchr(const void *s, int c, size_t n);
int memcmp(const void *s1, const void *s2, size_t n);
void *memcpy(void *dest, const void *src, size_t n);
void *memfrob(void *s, size_t n);
void *memmem(const void *needle, size_t needlelen,
const void *haystack, size_t haystacklen);
void *memmove(void *dest, const void *src, size_t n);
void *memset(void *s, int c, size_t n);
DESCRIPTION
The byte string functions perform operations on strings (byte arrays) that are not necessarily null-terminated. See the individual man
pages for descriptions of each function.
NOTES
The functions bcmp(), bcopy() and bzero() are obsolete. Use memcmp(), memcpy() and memset() instead.
SEE ALSO
bcmp(3), bcopy(3), bzero(3), memccpy(3), memchr(3), memcmp(3), memcpy(3), memfrob(3), memmem(3), memmove(3), memset(3)
