-.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.
