31 SCM ly_str02scm (char const*c);
32 SCM ly_symbol2scm (char const *);
33 String ly_scm2string (SCM s);
34 String ly_symbol2string (SCM);

36 Offset ly_scm2offset (SCM);
38 Interval ly_scm2interval (SCM);
39 SCM ly_interval2scm (Interval);
41 SCM ly_parse_scm (char const* s, int* n);
42 SCM ly_quote_scm (SCM s);
46 display and print newline.
48 void ly_display_scm (SCM s);
52 void read_lily_scm_file (String);
53 void init_lily_guile ();
58 these conversion functions also do a typecheck on the argument, and
59 return a default value if S has the wrong type.
