+.SH DESCRIPTION
+The
+.ZN XrmGetResource
+and
+.ZN XrmQGetResource
+functions retrieve a resource from the specified database.
+Both take a fully qualified name/class pair, a destination
+resource representation, and the address of a value
+(size/address pair).
+The value and returned type point into database memory;
+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.
