getuid get user identifications (getuid = 24.)
sys getuid getuid( ) returns a word (in r0), the low
byte of which contains the real user ID of the current
process. The high byte contains the effective user ID of the
current process. The real user ID identifies the person who
is logged in, in contradistinction to the effective user ID,
which determines his access permission at the moment. It is
thus useful to programs which operate using the
‘‘set user ID’’ mode, to find out
who invoked them. setuid (II)
