NAME

       pmNameAll - translate a PMID to a set of performance metric names

C SYNOPSIS

       #include <pcp/pmapi.h>

       int pmNameAll(pmID pmid, char ***nameset);

       cc ... -lpcp

DESCRIPTION

       Given a Performance Metric ID (PMID) via pmid, pmNameAll will determine all the corresponding metric names, if any, in the Performance Met-
       rics Name Space (PMNS), and return these via nameset.

       The resulting list of pointers nameset and the values (the relative names)  that  the  pointers	reference  will  have  been  allocated	by
       pmNameAll with a single call to malloc(3C), and it is the responsibility of the pmNameAll caller to free(nameset) to release the space when
       it is no longer required.

       In the absence of errors, pmNameAll returns the number of names in nameset.

       For many examples of a PMNS, there will be a 1:1 mapping between a name and a PMID, and under these circumstances, pmNameID(3)  provides  a
       slightly simpler interface in the absence of duplicate names for a particular PMID.

DIAGNOSTICS

       PM_ERR_NOPMNS
	      Failed to access a PMNS for operation.  Note that if the application hasn't a priori called pmLoadNameSpace(3) and wants to use  the
	      distributed PMNS, then a call to pmNameAll must be made after the creation of a context (see pmNewContext(3)).

       PM_ERR_PMID
	      pmid does not correspond to a defined PMID in the PMNS.

       PM_ERR_*
	      Other diagnostics are for protocol failures when accessing the distributed PMNS.
