NAME

       pmSetProcessIdentity - set process user and group id

C SYNOPSIS

       #include <pcp/pmapi.h>

       int pmSetProcessIdentity(const char *username);

       cc ... -lpcp

DESCRIPTION

       pmSetProcessIdentity  provides  a  platform-independent  method  to  set  the user id of a
       process to that matching username.

       If possible (when the caller is already running as root) pmSetProcessIdentity will set the
       group id of the process to that of the matching user, e.g. using username and getpwnam(3).

       A  return  value  of 0 indicates success, otherwise the return value is an error code that
       may be decoded with pmErrStr(3).

       pmSetProcessIdentity is most often used in conjunction with  pmGetUsername(3)  at  process
       start up.
