PMDESTROYCONTEXT(3) Library Functions Manual PMDESTROYCONTEXT(3)
pmDestroyContext - destroy a PMAPI context
#include <pcp/pmapi.h>
int pmDestroyContext(int handle);
cc ... -lpcp
An application using the Performance Metrics Application Program‐
ming 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 of performance metrics as created by
pmlogger(1).
pmDestroyContext destroys the PMAPI context identified by handle.
Typically this would imply some termination of a connection to a
PMCD or closing an archive file, and orderly clean-up.
The context must have been previously created using
pmNewContext(3) or pmDupContext(3).
On success, pmDestroyContext returns zero. If handle was the cur‐
rent 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 opera‐
tion that requires a PMAPI context.
PM_ERR_NOCONTEXT
handle does not identify a valid PMAPI context
PMAPI(3), pmDupContext(3), pmNewContext(3), pmUseContext(3) and
pmWhichContext(3).
