pmdaconnect
PMDACONNECT(3) Library Functions Manual PMDACONNECT(3)
NAME
pmdaConnect - establish a connection between a daemon PMDA and PMCD
C SYNOPSIS
#include <pcp/pmapi.h>
#include <pcp/impl.h>
#include <pcp/pmda.h>
void pmdaConnect(pmdaInterface *dispatch);
cc ... -lpcp_pmda -lpcp
DESCRIPTION
pmdaConnect initializes an IPC channel between a PMDA(3) and the pmcd(1) process on the local host. The type of the connection is depen-
dent on the e_io field of the pmdaExt structure:
pmdaPipe Use stdin/stdout to communicate; assumes this is a pipe created by pmcd before the PMDA(3) was launched.
pmdaInet Assume pmcd(1) will establish a connection to an IPv4 internet domain socket set up by the PMDA(3). The name or number of
the port must be specified in the e_sockname or e_port fields of the pmdaExt structure, respectively.
pmdaIPv6 Assume pmcd(1) will establish a connection to an IPv6 internet domain socket set up by the PMDA(3). The name or number of
the port must be specified in the e_sockname or e_port fields of the pmdaExt structure, respectively.
pmdaUnix Assume pmcd(1) will establish a connection to a unix domain socket set up by the PMDA(3). The port number must be specified
in the e_port field of the pmdaExt structure.
pmdaUnknown The initial value of e_io which defaults to using stdin/stdout.
The relevant pmdaExt fields are initialized by pmdaInit(3) and set by pmdaGetOpt(3), so most PMDAs should not need to access or modify
them.
DIAGNOSTICS
pmdaConnect will log the type of connection made to pmcd(1) if the PMAPI(3) debug control variable (pmDebug) has the DBG_TRACE_LIBPMDA flag
set.
If an error occurs that is unrecoverable, dispatch->status is set to a value less than 0, otherwise it is zero or positive.
CAVEAT
The PMDA must be using PMDA_INTERFACE_2 or later, as specified in the call to pmdaDaemon(3).
