NAME         top

       pmDelProfile  -  delete  instance(s)  from the current PMAPI instance

C SYNOPSIS         top

       #include <pcp/pmapi.h>

       int pmDelProfile(pmInDom indom, int numinst, int *instlist);

       cc ... -lpcp

DESCRIPTION         top

       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

       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.

DIAGNOSTICS         top

              indom was PM_INDOM_NULL and instlist was not empty

CAVEAT         top

       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
