pmUseContext - change current PMAPI context

#include<pcp/pmapi.h>intpmUseContext(inthandle);cc...-lpcp

       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 of performance metrics as created by pmlogger(1).

       Calling pmUseContext causes the current PMAPI context to be set to the context identified by handle.  The
       value of handle must be one returned from an earlier call to pmNewContext(3) or pmDupContext(3).

       Below  the PMAPI, all contexts used by an application are saved in their most recently modified state, so
       pmUseContext restores the context to the state it was in the last time the  context  was  used,  not  the
       state of the context when it was established.
