+therefore, you must not modify the data. +.LP +The database only frees or overwrites entries on +.ZN XrmPutResource , +.ZN XrmQPutResource , +or +.ZN XrmMergeDatabases . +A client that is not storing new values into the database or +is not merging the database should be safe using the address passed +back at any time until it exits. +If a resource was found, both +.ZN XrmGetResource +and +.ZN XrmQGetResource +return +.ZN True ; +otherwise, they return +.ZN False . +.LP +The +.ZN XrmQGetSearchList +function takes a list of names and classes +and returns a list of database levels where a match might occur. +The returned list is in best-to-worst order and +uses the same algorithm as +.ZN XrmGetResource +for determining precedence. +If list_return was large enough for the search list, +.ZN XrmQGetSearchList +returns +.ZN True ; +otherwise, it returns +.ZN False . +.LP +The size of the search list that the caller must allocate is +dependent upon the number of levels and wildcards in the resource specifiers +that are stored in the database. +The worst case length is %3 sup n%, +where \fIn\fP is the number of name or class components in names or classes. +.LP +When using +.ZN XrmQGetSearchList +followed by multiple probes for resources with a common name and class prefix, +only the common prefix should be specified in the name and class list to +.ZN XrmQGetSearchList . +.LP +The +.ZN XrmQGetSearchResource +function searches the specified database levels for the resource +that is fully identified by the specified name and class. +The search stops with the first match. +.ZN XrmQGetSearchResource +returns +.ZN True +if the resource was found; +otherwise, it returns +.ZN False . +.LP +A call to +.ZN XrmQGetSearchList +with a name and class list containing all but the last component +of a resource name followed by a call to +.ZN XrmQGetSearchResource +with the last component name and class returns the same database entry as +.ZN XrmGetResource +and +.ZN XrmQGetResource +with the fully qualified name and class. +.SH "MATCHING RULES" +The algorithm for determining which resource database entry +matches a given query is the heart of the resource manager. +All queries must fully specify the name and class of the desired resource +(use of the characters ``*'' and ``?'' are not permitted). +The library supports up to 100 components in a full name or class. +Resources are stored in the database with only partially specified +names and classes, using pattern matching constructs. +An asterisk (*) is a loose binding and is used to represent any number +of intervening components, including none. +A period (.) is a tight binding and is used to separate immediately +adjacent components. +A question mark (?) is used to match any single component name or class. +A database entry cannot end in a loose binding; +the final component (which cannot be the character ``?'') must be specified. +The lookup algorithm searches the database for the entry that most +closely matches (is most specific for) the full name and class being queried. +When more than one database entry matches the full name and class, +precedence rules are used to select just one. +.LP +The full name and class are scanned from left to right (from highest +level in the hierarchy to lowest), one component at a time. +At each level, the corresponding component and/or binding of each +matching entry is determined, and these matching components and +bindings are compared according to precedence rules. +Each of the rules is applied at each level before moving to the next level, +until a rule selects a single entry over all others. +The rules, in order of precedence, are: +.IP 1. 5 +An entry that contains a matching component (whether name, class, +or the character ``?'') +takes precedence over entries that elide the level (that is, entries +that match the level in a loose binding). +.IP 2. 5 +An entry with a matching name takes precedence over both +entries with a matching class and entries that match using the character ``?''. +An entry with a matching class takes precedence over +entries that match using the character ``?''. +.IP 3. 5 +An entry preceded by a tight binding takes precedence over entries +preceded by a loose binding. +.SH "SEE ALSO" +XrmInitialize(3X11), +XrmMergeDatabases(3X11), +XrmPutResource(3X11), +XrmUniqueQuark(3X11) +.br +\fI\*(xL\fP |
