3. ARGUMENTS ▲
bindings_return 1i Returns the binding list.
quark 1i Specifies the quark for which the equivalent string is desired.
quarks_return 1i Returns the list of quarks.
string 1i Specifies the string for which a quark\*(Ql is to be allocated.
4. DESCRIPTION ▲
The .ZN 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 .ZN XrmStringToQuark need not be permanently allocated storage. .ZN XrmPermStringToQuark is just like .ZN 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 .ZN XrmQuarkToString .
For any given quark, if .ZN 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, .ZN XrmQuarkToString returns NULL. For any given quark, if .ZN 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 .ZN XrmStringToQuark need not be permanently allocated storage. .ZN XrmPermStringToQuark is just like .ZN 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 .ZN XrmQuarkToString .
For any given quark, if .ZN XrmStringToQuark returns a non-NULL value, all future calls will return the same value (identical address).
The .ZN 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 .ZN 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 .ZN 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;
.ZN XrmBindTightly indicates that a period separates the components, and .ZN XrmBindLoosely indicates that an asterisk separates the components.
The .ZN 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 .ZN 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 |
