SYNOPSIS    [Toc]    [Back]

       #include <unistd.h>

               void ); uid_t geteuid(
               void );

       [Tru64  UNIX]   Application developers may want to specify
       an #include statement for <sys/types.h> before the one for
       <unistd.h>  if  programs  are  being develped for multiple
       platforms.  The  additional  #include  statement  is   not
       required  on  Tru64  UNIX  systems or by ISO or Open Group
       standards, but may be required on other  vendors'  systems
       that conform to these standards.
