int pmDelProfile(pmInDom indom, int numinst, int *instlist)
cc ... -lpcp
DESCRIPTION
The set of instances for performance metrics returned from a
pmFetch(3)
call may be filtered or restricted using an instance profile.
There is one instance profile for each context the application
creates at the Performance Metrics Application Programming Interface (PMAPI),
and each instance profile may include instances from one or more
instance domains (see
pmLookupDesc(3)).
pmDelProfile
may be used to
delete instance specifications from the instance profile of the current
PMAPI context.
In the simplest variant, the list of instances identified by the
instlist
argument for the
indom
instance domain are removed from the instance
profile.
The list of instance identifiers contains
numinst
values.
The
indom
value would normally be extracted from a call to
pmLookupDesc(3)
for a particular performance metric, and the instances in
instlist
would typically be determined by calls to
pmGetInDom(3)
or
pmLookupInDom(3).
If
indom
equals
PM_INDOM_NULL
or
numinst
is zero,
then all instance domains are selected for deletion. If
instlist
is
NULL,
then all instances in the selected domain(s) are removed
from the profile.
To disable all available instances in all domains, use
pmDelProfile(PM_INDOM_NULL, 0, NULL).
This is the only situation in which
indom
may be
PM_INDOM_NULL.
indom
was
PM_INDOM_NULL
and
instlist
was not empty
CAVEAT
It is possible to delete non-existent instance domains and non-existent
instances from an instance profile. None of the routines that use the instance
profile will ever issue an error if you do this. The cost of checking, when
checking is possible, outweighs any benefits.
