function headers and argument checking. Switched SCM_PROC,
SCM_PROC1 macros to be GUILE_PROC, GUILE_PROC1 (may change names
later, but was useful to keep old versions around while migrate)
that has docstrings and argument lists embedded in the GUILE_PROC
macro invocations that expand into a function header. Use lots of
new SCM_VALIDATE_* macros to simplify error checking and reduce
tons of redundancy. This is very similar to what I did for Scwm.
Note that none of the extraction of the docstrings, nor software
engineering checks of Scwm is yet added to Guile. I'll work on
that tomorrow, I expect.
* Makefile.am: Added scm_validate.h to modinclude_HEADERS.
* chars.c: Added docstrings for the primitives defined in here.
* snarf.h: Added GUILE_PROC, GUILE_PROC1. Added
SCM_REGISTER_PROC to be like old SCM_PROC, though old SCM_PROC
still remains for now. Changed naming convention for the s_foo
string name of the primitive to be s_scm_foo for ease of use with
the macro.
* scm_validate.h: Lots of new SCM_VALIDATE macros to simplify
argument checking through guile. Maybe some of these should be
folded into the header file for the types they check, but for now
it was easiest to just stick them all in one place.
(sysdep_dynl_link): Added `flags' argument.
(kw_global, sym_global): New.
(scm_dynamic_link): Handle keyword arguments. Pass suitable flags
to sysdep_dynl_link.
* dynl-dl.c (sysdep_dynl_link): Handle new `flags' argument by
conditrionally adding RTLD_GLOBAL to DLOPEN_MODES.
* dynl-shl.c (sysdep_dynl_link): Add and ignore new flags
argument.
* dynl-dld.c (sysdep_dynl_link): Add and ignore new flags
argument.
* dynl.h (scm_dynamic_link): Added rest argument.
* dynl.c (sysdep_dynl_unlink, sysdep_dynl_func): Use const
qualifier for char* argument, to match prototypes. Thanks to Mark
Elbrecht.
function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
(scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
call the sysdep functions with deferred ints.
* dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
deferred interrupts and insert SCM_ALLOW_INTS before throwing an
error.
* dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
SCM_UNSPECIFIED.
are now defined even when dynamic linking is not available for the
host system. Some of their functionality can be done without
dynamic linking; when it's really needed, they throw errors.
function in a dynamic object.
(scm_dynamic_call, scm_dynamic_args_call): Accept the values
produced by scm_dynamic_func as the thing to call.
* dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
(scm_register_module_xxx, scm_registered_modules,
scm_clear_registered_modules): New functions.
