The data types of the XOM service interface are defined in this topic and listed in the following table. These data types are repeated in the XOM reference pages (see xom.h(4xom) ).
XOM Service Interface Data Types
| Data Type | Description |
| OM_boolean | Type definition for a Boolean data value. |
| OM_descriptor | Type definition for describing an attribute type and value. |
| OM_enumeration | Type definition for an Enumerated data value. |
| OM_exclusions | Type definition for the exclusions parameter for om_get( ). |
| OM_integer | Type definition for an Integer data value. |
| OM_modification | Type definition for the modification parameter for om_put( ). |
| OM_object | Type definition for a handle to either a private or a public object. |
| OM_object_identifier | Type definition for an object identifier data value. |
| OM_private_object | Type definition for a handle to an object in an implementation-defined, or private, representation. |
| OM_public_object | Type definition for a defined representation of an object that can be directly interrogated by a programmer. |
| OM_return_code | Type definition for a value returned from all OM functions, indicating either that the function succeeded or why it failed. |
| OM_string | Type definition for a data value of one of the String syntaxes. |
| OM_syntax | Type definition for identifying a syntax type. |
| OM_type | Type definition for identifying an OM attribute type. |
| OM_type_list | Type definition for enumerating a sequence of OM attribute types. |
| OM_value | Type definition for representing any data value. |
| OM_value_length | Type definition for indicating the number of bits, octets, or characters in a string. |
| OM_value_position | Type definition for designating a particular location within a String data value. |
| OM_workspace | Type definition for identifying an application-specific API that implements OM, such as directory or message handling. |
· OM_sint
The positive and negative integers that can be represented in 16 bits
· OM_sint16
The positive and negative integers that can be represented in 16 bits
· OM_sint32
The positive and negative integers that can be represented in 32 bits
· OM_uint
The nonnegative integers that can be represented in 16 bits
· OM_uint16
The nonnegative integers that can be represented in 16 bits
· OM_uint32
The nonnegative integers that can be represented in 32 bits
Note: The OM_sint and OM_uint data types are defined by the range of integers they must accommodate. As typically declared in the C interface, they are defined by the range of integers permitted by the host machine's word size. The latter range, however, always encompasses the former.
The type definitions for these data types are as follows:
typedef int OM_sint;
typedef short OM_sint16;
typedef long int OM_sint32;
typedef unsigned OM_uint;
typedef unsigned short OM_uint16;
typedef long unsigned OM_uint32;
