declaration-information

Arguments: symbol &optional env

This function returns information about declarations named by symbol in the environment specified by env. The null lexical environment is used when env is unspecified or nil.

declaration-information only returns declarations that are not usually associated with a variable or function namespace. If the name or value of a variable or function has been given a declaration, then that declaration will not be retrieved by declaration-information, it will instead be retrieved by the appropriate variable-information or function-information call, and will be returned as an element of the third value returned.

When symbol is optimize, declaration-information returns a list whose elements are of the form (quality value) -- i.e. (space 2) or (speed 3) -- where the quality is one of the optimization qualities space, size, speed, compilation-speed, and debug, and the value is 0, 1, 2, or 3. This list is the single value returned. This list must not be modified.

When symbol is declaration, declaration-information returns a list whose elements are declaration names that have been proclaimed valid through the use of declaration proclamations. This list is the single value returned. This list must not be modified.
