 Name:         »Pgeteuid« - Get effective user ID of a process.

 Opcode:       312

 Syntax:       int32_t Pgeteuid ( void );

 Description:  The function Pgeteuid returns the effective user ID of 
               the current process and resembles the system call 
               Pgetuid. The difference lies in that here the effective 
               user ID is returned.

               This is normally identical to the actual user ID; 
               however, if a program is running that has set the 
               setuid bit, its effective user ID is equal to the 
               (actual) ID of the owner of this program file.

               File accesses are based, among other things, on the 
               effective user ID, so that the setuid mechanism allows 
               users (particularly the super-user) to permit access by 
               other users.

 Return value: The return value is the effective user ID of the 
               process.

 Availability: Available when a 'MiNT' cookie with a version of at 
               least 0.95 exists.
