Hi,
I use emacs 25.0.50.
I don't undersand call-process documentation in particular at
third argument nature. Documentation says that output might go
to a file but I can't understand how.
(call-process myproc nil myfile nil)
consider myfile as a string and sends output to a buffer name
with that string. That is not the result I wish.
(call-process myproc nil (:file myfile) nil) Says that make an
error saying that :file is not a function : I could have guess
that myself but in the documentation syntax is given as follows
: (:file FILE-NAME) : what might that mean !
(call-process myproc nil :file myfile nil) causes also an error
: wrong type arguments stringp nil.
Does anyone have an idea or should I investigate the code to
understand something ?
Regards

OK it means (list :file file-name) and it works. Sorry for
the noise !
