Members

irdaClassName

Null-terminated string that is the class name for an IAS object. Maximum of 60 characters.

irdaAttribName

Null-terminated string that is the attribute name for an IAS object. Maximum of 60 characters.

irdaAttribType

Attribute type, set to one of the values in the following table.

Value Description

IAS_ATTRIB_INT

Identifies an integer attribute value.

IAS_ATTRIB_OCTETSEQ

Identifies a binary, or octet, attribute value.

IAS_ATTRIB_STR

Identifies a string attribute value.
irdaAttribInt

32-bit signed integer attribute value.

Len(IAS_ATTRIB_OCTETSEQ)

Length of OctetSeqin octets, or bytes. It is a value from 0 through 1024.

OctetSeq(IAS_ATTRIB_OCTETSEQ)

A binary value to associate with irdaAttribName.

Len(IAS_ATTRIB_STR)

Length of UsrStr, in octets. It is a value from 0 through 255.

CharSet(IAS_ATTRIB_STR)

The selected character set. The following table shows the possible values.

Value Description

LmCharSetASCII

LmCharSetISO_8859_5

LmCharSetISO_8859_1

LmCharSetISO_8859_6

LmCharSetISO_8859_2

LmCharSetISO_8859_7

LmCharSetISO_8859_3

LmCharSetISO_8859_8

LmCharSetISO_8859_4

LmCharSetISO_8859_9
UsrStr(IAS_ATTRIB_STR)

User string to associate with irdaAttribName.

Reserved

This is used to DWORD-align the structure.

Remarks

If either the octet sequence specified in OctetSeqor the user string specified in UsrStris associated with irdaAttribName, it is necessary to allocate additional buffer space.

The Windows Embedded CE irdaClassNameand irdaAttribNamemembers have different maximum lengths than their Windows counterparts. The irdaAttribType, Len, and irdaAttribIntmembers also have different types.

The IAS_SETstructure does not contain the required buffer space for either the octet sequence attributes or user string sequence attributes. To ensure that the buffer is large enough to query all remote objects, the maximum required buffer is sizeof(IAS_SET)+ 1024, which is the maximum attribute value length for an octet sequence.

Requirements

Header af_irda.h
Windows Embedded CE Windows CE 2.0 and later
Windows Mobile Windows Mobile Version 5.0 and later
