In this case strncmp() is practical because I do not have to
write two different blocks for full match and prefix match (atleast 
until I have figured out function pointers).
strncmp() seems to be safe with a reasonable limit (it stops comparing 
after n bytes as far as I know)
strnlen() seems unnecessary as the whole program uses strlen()
