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.
