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
