#### 11.2.14 unexport [Function] ¶

`unexport` symbols &optional package ⇒ t

#### Arguments and Values:: ¶

symbols—a designator for a list of symbols.

package—a package designator.

The default is the current package.

#### Description:: ¶

unexport reverts external symbols in package to internal status; it undoes the effect of export.

unexport works only on symbols present in package, switching them back to internal status. If unexport is given a symbol that is already accessible as an internal symbol in package, it does nothing.

#### Examples:: ¶

     (in-package "COMMON-LISP-USER") ⇒  #<PACKAGE "COMMON-LISP-USER">
     (export (intern "CONTRABAND" (make-package 'temp)) 'temp) ⇒  T
     (find-symbol "CONTRABAND") ⇒  NIL, NIL
     (use-package 'temp) ⇒  T
     (find-symbol "CONTRABAND") ⇒  CONTRABAND, :INHERITED
     (unexport 'contraband 'temp) ⇒  T
     (find-symbol "CONTRABAND") ⇒  NIL, NIL

#### Side Effects:: ¶

Package system is modified.

#### Affected By:: ¶

Current state of the package system.

#### Exceptional Situations:: ¶

If unexport is given a symbol not accessible in package at all, an error of type package-error is signaled.

The consequences are undefined if package is the `KEYWORD` package or the `COMMON-LISP` package.
