XrmQuarkToString() XrmQuarkToString()
Name
XrmQuarkToString - convert a quark to a string.
Synopsis
char *XrmQuarkToString(quark)
XrmQuark quark;
Arguments
quark Specifies the quark for which the equivalent string is desired.
Returns
The string.
Description
XrmQuarkToString() returns the string for which the specified quark is serving as a shorthand symbol. The quark was earlier set to repre-
sent the string by XrmStringToQuark(). The string pointed to by the return value must not be modified or freed, because that string is in
the data structure used by the resource manager for assigning quarks. If no string exists for that quark, XrmQuarkToString() returns NULL.
Since the resource manager needs to make many comparisons of strings when it gets data from the database, it is more efficient to convert
these strings into quarks, and to compare quarks instead. Since quarks are represented by integers, comparing quarks is trivial.
The three #define statements in the Structures section provide an extra level of abstraction. They define macros so that names, classes
and representations can also be represented as quarks.

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. 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 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. 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 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 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. Component names in the list are separated by a period or an asterisk char- acter. 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 SEE ALSO
