Re: [PATCH] Scheme function ly:string->duration

[Neil Puttock]

Thanks for your comments, Joe.

I'm struggling a bit with sscanf () though. I tried your suggestion of

if (sscanf (s.c_str (), "%d") != s.size ()) ...

but it fails with a segfault; when compiling, I get two warnings: that
there's not enough arguments to sscanf (), and about type conversion
(shouldn't s.size () be cast as int for this comparison?)

It works OK (ignoring the cast) if I change it to

if (sscanf (s.c_str (), "%d", &len) != s.size ()) ...

but I'm a bit confused here: doesn't sscanf () return the number of
variables which have successfully been assigned values? If so, how can
the test work?

Thanks,
Neil
