Subject: Passing function to mapcar
Date: Sun, 01 Sep 2024 23:44:03 +0000	[thread overview]
Message-ID: <7gCipGlilClt_mxSbraoYACoR6rHzQFm-JCI_l8iT9Ql-dSYy5VArUWM5fl2gcKpLfKOnxWiC5VYS0ey7dQTvESkr1c8awVioFwSrJmEM-g=@protonmail.com> (raw)

I am using mapcar to apply the lambda function taking values
in rgb-list as argument c.

(mapcar (lambda (c)
          (min 255 (max 0 (round (* c factor)))))
        rgb-list)

I think that the function used for mapcar should have only a 
single argument.  Is this correct ?

What can one do if I want to call a function with more than 
a single argument ?

(defun myfunc (c factor)
  (min 255 (max 0 (round (* c factor)))))

(mapcar myfunc(c factor) rgb-list)
