ARGUMENTS

       bindings_return
                 Returns the binding list.

       quark     Specifies the quark for which the equivalent string is
                 desired.

       quarks_return
                 Returns the list of quarks.

       string    Specifies the string for which a quark or quark list is to be
                 allocated.

DESCRIPTION

       The XrmUniqueQuark function allocates a quark that is guaranteed not to
       represent any string that is known to the resource manager.

       These functions can be used to convert from string to quark
       representation.  If the string is not in the Host Portable Character
       Encoding, the conversion is implementation-dependent.  The string
       argument to XrmStringToQuark need not be permanently allocated storage.
       XrmPermStringToQuark is just like XrmStringToQuark, except that Xlib is
       permitted to assume the string argument is permanently allocated, and,
       hence, that it can be used as the value to be returned by
       XrmQuarkToString.

       For any given quark, if XrmStringToQuark returns a non-NULL value, all
       future calls will return the same value (identical address).

       These functions can be used to convert from quark representation to
       string.  The string pointed to by the return value must not be modified
       or freed.  The returned string is byte-for-byte equal to the original
       string passed to one of the string-to-quark routines.  If no string
       exists for that quark, XrmQuarkToString returns NULL.  For any given
       quark, if XrmQuarkToString returns a non-NULL value, all future calls
       will return the same value (identical address).

       These functions can be used to convert from string to quark
       representation.  If the string is not in the Host Portable Character
       Encoding, the conversion is implementation-dependent.  The string
       argument to XrmStringToQuark need not be permanently allocated storage.
       XrmPermStringToQuark is just like XrmStringToQuark, except that Xlib is
       permitted to assume the string argument is permanently allocated, and,
       hence, that it can be used as the value to be returned by
       XrmQuarkToString.

       For any given quark, if XrmStringToQuark returns a non-NULL value, all
       future calls will return the same value (identical address).

       The XrmStringToQuarkList function converts the null-terminated string
       (generally a fully qualified name) to a list of quarks.  The caller
       must allocate sufficient space for the quarks list before calling
       XrmStringToQuarkList.  Note that the string must be in the valid
       ResourceName format (see section 15.1).  If the string is not in the
       Host Portable Character Encoding, the conversion is implementation-
       dependent.

       A binding list is a list of type XrmBindingList and indicates if
       components of name or class lists are bound tightly or loosely (that
       is, if wildcarding of intermediate components is specified).

       typedef enum {XrmBindTightly, XrmBindLoosely} XrmBinding, *XrmBindingList;

       XrmBindTightly indicates that a period separates the components, and
       XrmBindLoosely indicates that an asterisk separates the components.

       The XrmStringToBindingQuarkList function converts the specified string
       to a binding list and a quark list.  The caller must allocate
       sufficient space for the quarks list and the binding list before
       calling XrmStringToBindingQuarkList.  If the string is not in the Host
       Portable Character Encoding the conversion is implementation-dependent.
       Component names in the list are separated by a period or an asterisk
       character.  If the string does not start with period or asterisk, a
       period is assumed.  For example, ``*a.b*c'' becomes:

       quarks     a       b
       bindings   loose   tight
