/* Name: adu_csnormalize - Normalizes a platform characterset
** string in the alias table or as obtained
** by CM_getcharset.
** Description:
**
** As per the Unicode technical report UTR22. Ref:
** http://www.unicode.org/reports/tr22/ section 1.4, recommended
** method to compare the alias values in an alias table to a character
** set is to normalize the string in following manner.
**
** 1. Delete all characters except a-z, A-Z, and 0-9.
** 2. Map uppercase A-Z to the corresponding lowercase a-z.
** 3. From left to right, delete each 0 that is not preceded by a digit.
**
** For example, the following names should match: "UTF-8", "utf8",
** "u.t.f-008", but not "utf-80" or "ut8".
**
** Input:
** instring - Unnormalized converter name string.
**
** Output:
** instring - Normalized converter name string.
**
** History:
** 23-Jan-2004 (gupsh01)
** Added.

** Name: MOdetach - detach an attached instance
**
** Description:
**
** Detaches an attached instance. Subsequent attempts to get or

**
** Frees memory allocated by MOattach using MEfree.
**
** If the call succeeds, it must also call the monitors for the

** value.
**
** Inputs:
** classid
** the classid of the object.
** instance
** the instance of the object.
** Outputs:
** none
** Returns:
** OK
** if the classid was detached.
** MO_NO_INSTANCE
** if classid is not attached.
** MO_NO_DETACH
** if the object was attached as MO_PERMANENT.
**
** History:
** 15-jul-92 (daveb)
** Go back to single-instance attach/detach, as with
** MOcdata_index most bulky static one-offs will be
** right in the class definitions anyway, and this
** is simpler for the dynamic attach.
** 02-sep-1999 (somsa01)
