ARGUMENTS
bindings_return
Returns the binding list.
quark Specifies the quark for which the equivalent string is de-
sired.
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 representa-
tion. 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. Xrm-
PermStringToQuark 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 XrmQuark-
ToString.
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 ex-
ists 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 representa-
tion. 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. Xrm-
PermStringToQuark 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 XrmQuark-
ToString.
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 Xrm-
StringToQuarkList. Note that the string must be in the valid Resource-
Name format (see section 15.1). If the string is not in the Host Por-
table Character Encoding, the conversion is implementation-dependent.
A binding list is a list of type XrmBindingList and indicates if compo-
nents 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 suffi-
cient 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. Compo-
nent names in the list are separated by a period or an asterisk charac-
ter. 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
