Re: [fpc-pascal] [SYSTEM]: How detecting if run as root ?
Many thanks i found the function GetEUID i'll try it http://www.cs.uwc.ac.za/~firstyear/manuals/doc/units/unitsse36.html#x53-41900012.3 Pete Cervasio a écrit : On Wednesday 11 October 2006 20:44, Michalis Kamburelis wrote: Pete Cervasio wrote: The better way would be to use the geteuid function in the libc unit, It would be even better to use FpGetEUid function from the BaseUnix unit.

Dear
I need to detect if the program is executed as root privileges on Linux
system.
Did somebody had developped a such function ??
Best regards.
Well you can try GetEnv('USER') = 'root'; or GetEnv('UID') = '0'; but
there may be better ways to check this.

The better way would be to use the geteuid function in the libc unit, because
the environment variables may not be set (such as if they were explictly
unset or if the program is run from cron or the system startup scripts).
See the getuid/geteuid man page for particulars. And no, I am not saying
RTFMP spitefully. :) :)
Best regards,

It would be even better to use FpGetEUid function from the BaseUnix
unit. See [http://www.freepascal.org/docs-html/rtl/baseunix/fpgeteuid.html].
