Vl-split-define-text

Split up the rest of a define line into macro arguments and macro text.

Signature

(vl-split-define-text text config) 
  → 
(mv successp formals body)

Arguments

text — The text that occurs after `define foo, perhaps including any macro arguments such as (a,b) in the case of macros such as `define max(a,b) ....
    Guard (vl-echarlist-p text).

config — Guard (vl-loadconfig-p config).

Returns

successp — Type (booleanp successp).

formals — Type (vl-define-formallist-p formals).

body — Remaining characters after any macro arguments.
    Type (vl-echarlist-p body), given (force (vl-echarlist-p text)).
