An application using the Performance Metrics Application Programming
Interface (PMAPI) may manipulate several concurrent contexts, each
associated with a source of performance metrics, e.g. pmcd(1) on some
host, or an archive log of performance metrics as created by
pmDestroyContext destroys the PMAPI context identified by handle.
Typically this would imply some termination of a connection to a PMCD
or closing an archive log file, and orderly clean-up.
The context must have been previously created using pmNewContext(3)
On success, pmDestroyContext returns zero. If handle was the current
PMAPI context, then the current context becomes undefined. This
means the application must explicitly re-establish a valid PMAPI
context with pmUseContext(3), or create a new context with
pmNewContext(3) or pmDupContext(3), before the next PMAPI operation
that requires a PMAPI context.
