Function: `cl-decf`

cl-decf is a function alias for decf, defined in gv.el.gz.

Signature

(cl-decf ARG1 &optional ARG2)

Decrement PLACE by X (1 by default).

PLACE may be a symbol, or any generalized variable allowed by setf. The return value is the decremented value of PLACE.

If X is specified, it should be an expression that should evaluate to a number.

This macro is considered deprecated in favor of the built-in macro decf that was added in Emacs 31.1.

Probably introduced at or before Emacs version 31.1.
