IAS_SET (Windows Embedded CE 6.0)

1/6/2010

This structure contains data for creating an Information Access Service (IAS) object.

Syntax

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 Embedded 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.
