Not Collective

Input Parameters

t - pointer to string
n - the length to copy

Output Parameter

s -the copied string

If the string that is being copied is of length n or larger then the entire string is not copied and the file location of s is set to NULL. This is different then the behavior of strncpy() which leaves s non-terminated.
