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 |
