pmGetUsername - fetch special PCP username
#include <pcp/pmapi.h>
int pmGetUsername(char **username)
cc ... -lpcp
Within the Performance Co-Pilot (PCP) some applications use a special
(non-root) username to allow access, e.g. to write log files into
protected directories.
pmGetUsername returns the name via username.
The variable name PCP_USER is fetched using pmGetOptionalConfig(3).
If this succeeds, pmGetUsername returns 1. Otherwise. username is
set to the default value of pcp and pmGetUsername returns 0.
pmGetUsername is most often used in conjunction with
pmSetProcessIdentity(3) at process start up.
PMAPI(3), pmGetOptionalConfig(3) and pmSetProcessIdentity(3).
