                     13: called the  real group identifier  and the effective  group iden-
                     14: tifier.   The group identifiers  determine eligibility  to access
                     15: files and use system privileges.  Normally, these two identifiers
                     16: are identical.   However, for a set  group identifier load module
                     17: (see exec), the real group identifier is that of the group's cur-
                     18: rent group, whereas the effective group identifier is that of the
                     19: load module  owner.  This  distinction allows system  programs to
                     20: use  files  which  are  protected  from  groups that  invoke  the
                     21: program.
                     22: 
                     23: getegid returns the effective group identifier.
