Module Name:

    shimdb.h

Abstract:

    header for the database file access functions used by the App Compat shimming system

Author:

    dmunsil 02/02/2000

Revision History:

Notes:

    This "database" is more of a tagged file, designed to mimic the structure of an XML
    file. An XML file can be converted into this packed data format easily, and all strings
    will by default be packed into a stringtable and referenced by a DWORD identifier, so files
    that contain a lot of common strings (like the XML used by the App Compat tema) will not
    bloat.

    To see the actual tags used by the shimdb, look in shimtags.h.

    For the high-level interface used by the loader in NTDLL, look at ntbaseapi.c

// TAG TYPES
//

//
// The most significant 4 bits tell you the basic type and size of data,
// and the lower 12 are the specific tag.
//
// In this way, even if we add more tags to the db, older readers can read
// the data because the type is either implied (for the first 5 types)
// or supplied (for all other types).
//
// WARNING: it is important that only the first 5 types have implied sizes.
// any future types should use a size or backwards compatibility will not be
// maintained.

//
// The following tags have an implied size.
//
#define TAG_TYPE_NULL           0x1000  // implied size 0
#define TAG_TYPE_BYTE           0x2000  // implied size 1
#define TAG_TYPE_WORD           0x3000  // implied size 2
#define TAG_TYPE_DWORD          0x4000  // implied size 4
#define TAG_TYPE_QWORD          0x5000  // implied size 8
#define TAG_TYPE_STRINGREF      0x6000  // implied size 4, for strings that should be tokenized

//
// These tags have a size after them (the size is type TAG_OFFSET)
//
#define TAG_TYPE_LIST           0x7000
#define TAG_TYPE_STRING         0x8000
#define TAG_TYPE_BINARY         0x9000


#define TAGREF_NULL 0
#define TAGREF_ROOT 0


//
// Special define for stripping out just the type from a tag.
//
#define TAG_STRIP_TYPE          0xF000

//
// This macro strips off the lower bits of the TAG and returns the upper bits, which
// give the basic type of tag. All the tag types are defined above.
//
// The type info is purely used internally by the DB to tell whether the tag has
// an implied size, or if the DB needs to do something special with the data before
// handing it back to the caller.
