The Process::Sys module contains UID and GID functions which provide direct bindings to the system calls of the same names instead of the more-portable versions of the same functionality found in the Process, Process::UID, and Process::GID modules.
Returns the effective group ID for this process. Not available on all platforms.
Process.egid #=> 500
/* * call-seq: * Process.egid => fixnum * Process::GID.eid => fixnum * Process::Sys.geteid => fixnum * * Returns the effective group ID for this process.

Returns the effective user ID for this process.
Process.euid #=> 501
/* * call-seq: * Process.euid => fixnum * Process::UID.eid => fixnum * Process::Sys.geteuid => fixnum * * Returns the effective user ID for this process. * * Process.euid #=> 501 */ static VALUE proc_geteuid(obj) VALUE obj; { int euid = geteuid(); return INT2FIX(euid); }
Returns the (real) group ID for this process.

Returns true if the process was created as a result of an execve(2) system call which had either of the setuid or setgid bits set (and extra privileges were given as a result) or if it has changed any of its real, effective or saved user or group IDs since it began execution.

Sets the (integer) real and/or effective group IDs of the current process to rid and eid, respectively. A value of -1 for either means to leave that ID unchanged. Not available on all platforms.
