uuid_gen Command (NCS)

Purpose

Generates Universal Unique Identifiers (UUIDs) for objects, types, and interfaces.

Syntax

/etc/ncs/uuid_gen [  -c ] [  -p ] [  -C ] [  -P ]

Description

The uuid_gen program generates Universal Unique Identifiers (UUIDs). By default, it generates a character-string representation of a UUID. The options for uuid_gen enable you to generate source-code representations of UUIDs, suitable for initializing variables of type uuid_$t.

Flags

Examples

1. To generate a character-string representation of a UUID, enter the following:

   /etc/ncs/uuid_gen

   This produces the following output:

   34dc23469000.0d.00.00.7c.5f.00.00.00
     

2. To generate a template for an interface definition in the C syntax, enter:

   /etc/ncs/uuid_gen -c

   This produces the following output:

   %c
   [
   uuid(34dc239ec000.0d.00.00.7c.5f.00.00.00),
   version(1)
   ]
   interface INTERFACENAME {
    
   }

3. To generate a C source-code representation of a UUID, enter the following:

   /etc/ncs/uuid_gen -C

   This produces the following output:

   = { 0x34dc23af,
       0xf000,
       0x0000,
       0x0d,
       {0x00, 0x00, 0x7c, 0x5f, 0x00, 0x00, 0x00} };

4. To generate a template for an interface definition in the Pascal syntax, enter the following:

   /etc/ncs/uuid_gen -p

   This produces the following output:

   %pascal
   [
   uuid (458487b55160.02.c0.64.02.03.00.00.00),
   version (1)
   ]
   interface INTERFACENAME;
    
   end;

5. To generate a Pascal source-code representation of a UUID, enter the following:

   /etc/ncs/uuid_gen -P

   This produces the following output:

   := [
       time_high := 16#458487df,
       time_low := 16#9fb2,
       reserved := 16#000,
       family := chr(16#02),
       host := [chr(16#c0), chr(16#64), chr(16#02), chr(16#03),
                chr(16#00), chr(16#00), chr(16#00)]
       ]
