Arguments: (&key block non-smp) &body body
This macro expands into code that uses a unique basic-lock associated with the expansion to control execution of the body code. Only one process at a time can acquire ownership of the lock and execute the forms in body. Ownership of the lock is relinquished when control leaves body by falling through or by non-local exit. The result of evaluating the critical-section code is the result of the last form in body.
The arguments are:
:without-scheduling: to get the equivalent of
(mp:without-scheduling . body)
:without-interrupts: to get the equivalent of
(excl:without-interrupts . body)
:atomically: to get the equivalent of
(excl::atomically . body)
See smp.htm and multiprocessing.htm for more information on this macro and on multiprocessing.
