Executes code while impersonating the client of the named pipe.

Package

win32

Signature

impersonating-named-pipe-client (named-pipe-stream &key fail-form fail-no-read-form) &body body

Arguments

named-pipe-stream⇩	A named pipe stream.
fail-form⇩	A Lisp form.
fail-no-read-form⇩	A Lisp form.
body⇩	Lisp forms.

Description

The macro impersonating-named-pipe-client executes the code of body while impersonating the client of the named pipe.

named-pipe-stream must be the result of open-named-pipe-stream.

For the impersonation to work, some input must have already been read from the pipe. If impersonation is used on a named pipe from which nothing was read, it calls error unless fail-no-read-form is supplied, in which case it executes this form. For all other kinds of failure fail-form is executed.

Apart from mechanism used to find the user to impersonate, impersonating-named-pipe-client behaves identically to impersonating-user. See impersonating-user for further details.

Notes

The limitation that some input must have been read is an undocumented restriction in the underlying Microsoft Windows functions.
