Subject: doc subr rest arg
Date: Thu, 21 Apr 2005 08:25:27 +1000	[thread overview]
Message-ID: <8764yhgk6g.fsf@zip.com.au> (raw)

I added a bit to scm_c_define_gsubr about not changing the rest arg.


Existing:
     If RST is non-zero, then any arguments after the first `REQ + OPT'
     are packaged up as a list and passed as FUNCTION's last argument.

Add:

     FUNCTION must not modify that list.  (Because when subr is called
     through `apply' the list comes directly from the `apply' list
     argument.  This list is copied when dispatching to a scheme
     procedure, but not when going to a subr.)
