Описание (Description)
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.
