getgid get group identifications (getgid = 47.; not in
assembler)
sys getgid getgid( ) returns a word (in r0), the low
byte of which contains the real group ID of the current
process. The high byte contains the effective group ID of
the current process. The real group ID identifies the group
of the person who is logged in, in contradistinction to the
effective group ID, which determines his access permission
at the moment. It is thus useful to programs which operate
using the ‘‘set group ID’’ mode, to
find out who invoked them. setgid (II)
