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


       #include <pcp/pmapi.h>

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

       cc ... -lpcp


       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 and 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.


       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


              indom was PM_INDOM_NULL and instlist was not empty
