Предостережение (Caveat)
This documentation is intended for internal Performance Co-Pilot
(PCP) developer use.
These interfaces are not part of the PCP APIs that are guaranteed
to remain fixed across releases, and they may not work, or may
provide different semantics at some point in the future.
Описание (Description)
Refer to PMAPI(3) for general information about the external
interfaces defined in <pcp/pmapi.h>. The interfaces described
here assume that context.
Многопоточные приложения (Multi-threaded applications)
The following groups of internal functions and services in libpcp
are restricted to being called from a single-thread, and this is
enforced by returning PM_ERR_THREAD when an attempt to call the
routines in each group from more than one thread is detected.
1. The interval timer services use global state with semantics
that demand it is only used in the context of a single
thread, so __pmAFregister(3), __pmAFunregister(3),
__pmAFblock(3), __pmAFunblock (3) and __pmAFisempty(3).
2. The following access control manipulation routines that are
principally intended for single-threaded applications:
__pmAccAddOp, __pmAccSaveHosts, __pmAccRestoreHosts,
__pmAccFreeSavedHosts, __pmAccAddHost, __pmAccAddClient,
__pmAccDelClient and __pmAccDumpHosts.
3. The following routines that identify pmlogger control ports
and are principally intended for single-threaded
applications: __pmLogFindPort and __pmLogFindLocalPorts.
