pmdaOpenLog - redirect stderr to a logfile

void pmdaOpenLog(pmdaInterface *
dispatch);
cc ... -lpcp_pmda -lpcp
pmdaOpenLog redirects
stderr to the logfile specified in the
dispatch structure, set by the previous call to
pmdaDaemon(3) or
pmdaGetOpt(3). The first line of the log file will detail the name of
the calling process, the host the process is running on, and the current time.
In addition, the log is appended with the exit time of the process by a
routine registered with
atexit(3).
The PMDA must be using
PMDA_PROTOCOL_2 or later, as specified in the call
to
pmdaDSO(3) or
pmdaDaemon(3).
Environment variables with the prefix
PCP_ are used to parameterize the
file and directory names used by PCP. On each installation, the file
/etc/pcp.conf contains the local values for these variables. The
$PCP_CONF variable may be used to specify an alternative configuration
file, as described in
pcp.conf(5). Values for these variables may be
obtained programmatically using the
pmGetConfig(3) function.
