gnus-mapcar

gnus-mapcar is a Lisp macro in `gnus-util.el'.

(gnus-mapcar FUNCTION SEQ1 &rest SEQS2_N)

Apply FUNCTION to each element of the sequences, and make a list of the results.
If there are several sequences, FUNCTION is called with that many arguments,
and mapping stops as soon as the shortest sequence runs out. With just one
sequence, this is like `mapcar'. With several, it is like the Common Lisp
`mapcar' function extended to arbitrary sequence types.
