IAS_SET (Windows CE 5.0)
This structure contains data for creating an Information Access Service (IAS) object.
typedef struct _IAS_SET {char irdaClassName[61];char irdaAttribName[61];u_short irdaAttribType; union { int irdaAttribInt; struct { int Len; u_char OctetSeq[1]; u_char Reserved[3];
} irdaAttribOctetSeq; struct { int Len; u_char CharSet; u_char UsrStr[1]; u_char Reserved[2]; } irda AttribUsrStr; } irdaAttribute;} _IAS_SET, *PIAS_SET;
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 OctetSeq in 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 OctetSeq or the user string specified in UsrStr is associated with irdaAttribName, it is necessary to allocate additional buffer space.
The Windows CE irdaClassName and irdaAttribName members have different maximum lengths than their Windows counterparts. The irdaAttribType, Len, and irdaAttribInt members also have different types.
The IAS_SET structure 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
OS Versions: Windows CE 2.0 and later.
