$Revision: 5.0.2.2 $

Function

Package: EXCL

Arguments: (package)

Returns t or nil as package is or is not locked. package must be a package object (it cannot be a symbol or a string). setf may be used with this function to lock or unlock a package.

Even if a package is package-locked, no error will be signaled when

the value of excl:*enable-package-locked-errors* is nil;
the violation is dynamically inside the body of a call to the macro excl:without-package-locks; or
the value of cl:*package* is the package being operated on.

See packages.htm for general information on the implementation of packages in Allegro CL and see 5.1 Package locking in that document for more information on package locking.
