pmdaDSO - initialize the PMDA to run as a DSO
int pmdaDSO(pmdaInterface *dispatch, int interface, char *name, char
cc ... -lpcp_pmda -lpcp
pmdaDSO initializes the pmdaInterface structure to use the interface
extensions, assuming the PMDA(3) is to be run as a DSO. The
pmdaInterface structure is initialized with:
name The name of the agent.
helptext The default path to the help text (see pmdaText(3). If
no help text is installed, or you are not using
pmdaText(3), then this should be set to NULL.
The callbacks are initialized to pmdaProfile(3), pmdaFetch(3),
pmdaDesc(3), pmdaText(3), pmdaInstance(3) and pmdaStore(3).
The interface structure also contains the domain of the PMDA(3), which
is defined in the pmcd(1) configuration file. The domain is used to
initialize the metric and instance descriptors (see pmdaInit(3)).
Incompatible version of pmcd detected
When pmcd(1) creates the pmdaInterface structure, the
dispatch.comm.version field is set to the highest
protocol that pmcd(1) understands. This message
indicates that the pmcd(1) process does not understand
the protocol used by pmdaDSO.
Unable to allocate memory for pmdaExt structure
In addition, dispatch->status is set to a value less
The PMDA must be using PMDA_INTERFACE_2 or later.
pmcd(1), PMAPI(3), PMDA(3), pmdaDaemon(3), pmdaInit(3) and pmdaText(3).
