[cffi-devel] implicit defbitfield symbol values
by Stephen Compall 12 May '06

12 May '06

Saw this was documented but not implemented.... http://scompall.nocandysw.com/cffi/implicit-defbitfield-values.darcs.patch Thu May 11 02:21:06 CDT 2006 Stephen Compall <scompall(a)nocandysw.com> * implicit defbitfield symbol values - Foreign Type Translators: defctype does not create Lisp types; you have to use eql specializers. - enum.lisp: Use reduce in %foreign-bitfield-value. Code a default rule for bitfield symbol values. -- Stephen Compall http://scompall.nocandysw.com/blog

[cffi-devel] Calculating size of C struct .?!
by Frank Goenninger 10 May '06

10 May '06

Hi again ;-) I do have the following C struct: typedef unsigned long tcflag_t; typedef unsigned char cc_t; typedef long speed_t; /* XXX should be unsigned long */ struct termios { tcflag_t c_iflag; /* input flags */ tcflag_t c_oflag; /* output flags */ tcflag_t c_cflag; /* control flags */ tcflag_t c_lflag; /* local flags */ cc_t c_cc[NCCS]; /* control chars */ speed_t c_ispeed; /* input speed */ speed_t c_ospeed; /* output speed */ }; with NCCS being #define'd to 20. I need to allocate space for this struct and therefore want to know its size ... As I don't need the struct itself I thought about calculating the size but I figure there's the problem of getting all the padding to count to the size... How would I do that ? Thx!! Frank

[cffi-devel] CFFI and CLSQL
by Ricardo Boccato 04 May '06

04 May '06

Hi, I am trying to use CLSQL with CFFI and I bumped into an error while trying to connect to an Oracle 9i database. I am using clisp but the same error ocurred with allegro 7 (trial). Basically, issuing the command: (asdf:oos 'asdf:load-op :clsql-oracle) yields this at the debugger: APPLY: too few arguments given to #<compiled-function #:|150 152 (cffi:define-foreign-type uffi-char (base-type) ...)-10-1-1|> [Condition of type system::simple-program-error] I found out that making the following changes to the code seems to solve the problem... computador:~/lib/cffi$ darcs diff diff -rN old-cffi/uffi-compat/uffi-compat.lisp new-cffi/uffi-compat/uffi-compat.lisp 112,113c112,113 < (:char '(uffi-char :char)) < (:unsigned-char '(uffi-char :unsigned-char)) --- > (:char :char) > (:unsigned-char :unsigned-char) ...but since I am new to lisp (and to cffi...and to clsql...;-) I really have no idea of what I am doing. :-) Thanks very much. []s, Ricardo Boccato Alves.
