NAME         top

       pmdaInterfaceMoved - reset internal state of a pmdaInterface
       structure

C SYNOPSIS         top

       #include <pcp/pmapi.h>

       void pmdaInterfaceMoved(pmdaInterface *dispatch)

       cc ... -lpcp_pmda -lpcp

DESCRIPTION         top

       After a call to either pmdaDaemon(3) or pmdaDSO(3) to initialize
       the pmdaInterface structure, if the caller needs to relocate or
       move the structure for any reason then pmdaInterfaceMoved needs
       to be called with the new base address of the pmdaInterface
       routine as specified by dispatch.

       pmdaInterfaceMoved will re-establish the internal integrity of
       the pmdaInterface structure at the new location before any other
       routine in libpcp_pmda called.
