/*++
Routine Description:
TurnRegStringIntoHandle converts the script's reg syntax into a cobra
object.
Arguments:
String - Specifies the registry key and value in the script syntax.
The string must be in the following format:
<root>\<key>\* [<value>]
Each part is optional.
<root> specifies HKCU, HKR, HKLM or HKCC.
<key> specifies a subkey (such as Software\Microsoft\Windows)
* specifies all subkeys. If <value> is not specified, then all
values and subvalues are also included.
<value> specifies a specific value name
Pattern - Specifies TRUE if the registry string can contain a pattern, or
FALSE if it cannot.
HadLeaf - Receives TRUE if String contains a leaf specification, FALSE
otherwise
Return Value:
A handle to a cobra object string, or NULL if parsing failed.

MIG_OBJECTSTRINGHANDLE
TurnFileStringIntoHandle (
IN PCTSTR String,

/*++
Routine Description:
TurnFileStringIntoHandle converts a file specification from the script
syntax into a cobra object.
Arguments:
String - Specifies the file string in the script syntax.
The string must be in the following format:
<directory>\<file>
Both parts are optional. The Flags member indicates how String
is parsed.
Flags - Specifies zero or more of the following flags:
PFF_NO_PATTERNS_ALLOWED - String cannot contain any wildcard
characters.
PFF_COMPUTE_BASE - Returns the directory portion of the string,
and truncates the directory at the first
wildcard if necessary. Truncation is done
at the backslashes only.
PFF_NO_SUBDIR_PATTERN - Do not include a trailing \*, even if
it was specified in String.
PFF_NO_LEAF_PATTERN - Do not include a * for the leaf when
String does not contain a file name.
If a file name is specified, include it.
PFF_PATTERN_IS_DIR - String does not specify a file name. It
is a directory only. The leaf portion of
the object string will be a *.
PFF_NO_LEAF_AT_ALL - Will return an object string that has a
node only, and no leaf specified at all.
Return Value:
A cobra object handle, or NULL if conversion failed.
