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       c
       bindings   loose   tight   loose
