io/foreign

Higher-level wrappers around the LuaJIT ffi module.

(define-foreign-function name lambda-list do-errno-check)

Macro defined at lib/io/foreign.lisp:8:2

Define a foreign function wrapper for the C symbol NAME, taking arguments LAMBDA-LIST.

Additionally, if DO-ERRNO-CHECK is true or a number, assume that negative return values (or the number, if given) signal an error condition, and raise an exception with the message determined by strerror(3).

The symbol NAME will be mangled by replacing -s with _s. If this is undesirable, you may give an argument of the form (quote foo), in which foo will not be mangled.

Example:

> (ffi/cdef "char *get_current_dir_name(void);")
out = nil
> (define-foreign-function get-current-dir-name () 0)
out = function: 0x42e22188
> (get-current-dir-name)
out = cdata<char *>: 0x00d26610
> (ffi/string (get-current-dir-name))
out = "/home/hydraz/Projects/urn/compiler"

(define-foreign-functions c-definitions &functions)

Macro defined at lib/io/foreign.lisp:61:2

Declare all the foreign functions specified in C-DEFINITIONS, and additionally build the wrappers as described in FUNCTIONS, using define-foreign-function

(ffi/defun-ffi name typedecl)

Macro defined at lib/luajit/ffi.lisp:22:2

Warning: ffi/defun-ffi is deprecated: Use cdef and index the C table directly

Define the external symbol NAME with the C type signature given by TYPEDECL.
