[Sablevm-developer] I think I know where the problem is...

Hi Brent.

You set up your main loop:

while ((start = fgets (start, MAXPATHLENGTH, file)))
...

It does not do what you meant.

fgets is a pain to work with, but it is feasible;  when you use it, you
have a few things to consider:

in [ s = fgets(...,MAX,...) ]

(1) if s == NULL: we have reached EOF
(2) while (s != NULL) && (strlen(s) == MAX - 1) && (s[MAX-2] != '\n')
     accumulate the option text!
(3) else s is a single line (or the tail of)

I suggest that you first accumulate the complete line (with a function).

Why not define a getline() function (using fgets)?  Do NOT read/copy the
definition of the libc library, as it might conflict with SableVM's
copyright notice.  [Unless you build a separate library for it, based on
glibc].

Also, you had an extra "len" variable declaration that was probably in
the way...
