If an application needs to know where the Performance Metrics Name
Space (PMNS) is coming from then pmGetPMNSLocation will return
whether it is from an archive, PMNS_ARCHIVE, or from a local PMNS
file, PMNS_LOCAL, or from a remote pmcd, PMNS_REMOTE.
This information may be useful in determining an appropriate error
message depending on the PMNS' location.
Environment variables with the prefix PCP_ are used to parameterize
the file and directory names used by PCP. On each installation, the
file /etc/pcp.conf contains the local values for these variables.
The $PCP_CONF variable may be used to specify an alternative
configuration file, as described in pcp.conf(5). Values for these
variables may be obtained programmatically using the pmGetConfig(3)
