GETUID(2)                                                            GETUID(2)



NAME
       getuid, geteuid - get user identity

SYNOPSIS
       #include <sys/types.h>

       uid = getuid()
       uid_t uid;

       euid = geteuid()
       uid_t euid;

DESCRIPTION
       _G_e_t_u_i_d  returns  the  real  user ID of the current process, _g_e_t_e_u_i_d the
       effective user ID.

       The real user ID identifies the person who is logged in.  The effective
       user  ID  gives  the process additional permissions during execution of
       “set-user-ID” mode processes, which use _g_e_t_u_i_d to determine  the  real-
       user-id of the process that invoked them.

SEE ALSO
       getgid(2), setreuid(2)
