XT FUNCTIONS XtResolvePathname(3xt)
NAME
XtResolvePathname - search for a file using standard substi-
tution SYNTAXcc [ flag... ] file... -lXt [ library... ]
String XtResolvePathname(Display *display, String type,
String filename, String suffix, String path, Substitu-
tion substitutions, Cardinal num_substitutions,
XtFilePredicate predicate); ARGUMENTS display Specifies the display to use to find the language for language substitutions. type filename suffix Specify values to substitute into the path. path Specifies the list of file specifications, or NULL. substitutions Specifies a list of additional substitutions to make into the path, or NULL.num_substitutions
Specifies the number of entries in substitu-
tions. predicate Specifies a procedure called to judge each potential file name, or NULL.DESCRIPTION
The substitutions specified by XtResolvePathname are deter-
mined from the value of the language string retrieved by XtDisplayInitialize for the specified display. To set the language for all applications specify ``*xnlLanguage: lang'' in the resource database. The format and content of thelanguage string are implementation-defined. One suggested
syntax is to compose the language string of three parts; a ``language part'', a ``territory part'' and a ``codesetpart''. The manner in which this composition is accom-
plished is implementation-defined and the Intrinsics make no
interpretation of the parts other than to use them in sub-
stitutions as described below.XtResolvePathname calls XtFindFile with the following sub-
stitutions in addition to any passed by the caller and returns the value returned by XtFindFile: X Version 11 Last change: libXt 1.0.8 1XT FUNCTIONS XtResolvePathname(3xt)
%N The value of the filename parameter, or the
application's class name if filename is NULL.%T The value of the type parameter.
%S The value of the suffix parameter.
%L The language string associated with the specified
display.%l The language part of the display's language string.
%t The territory part of the display's language string.
%c The codeset part of the display's language string.
%C The customization string retrieved from the resource
database associated with display.%D The value of the implementation-specific default path.
If a path is passed to XtResolvePathname, it will be passed
along to XtFindFile. If the path argument is NULL, the value of the XFILESEARCHPATH environment variable will be passed to XtFindFile. If XFILESEARCHPATH is not defined, animplementation-specific default path will be used which con-
tains at least 6 entries. These entries must contain the following substitutions:1. %C, %N, %S, %T, %L or %C, %N, %S, %T, %l, %t, %c
2. %C, %N, %S, %T, %l
3. %C, %N, %S, %T
4. %N, %S, %T, %L or %N, %S, %T, %l, %t, %c
5. %N, %S, %T, %l
6. %N, %S, %T
The order of these six entries within the path must be as given above. The order and use of substitutions within a given entry is implementation dependent. If the path beginswith a colon, it will be preceded by %N%S. If the path
includes two adjacent colons, %N%S will be inserted between
them. The type parameter is intended to be a category of files, usually being translated into a directory in the pathname.Possible values might include ``app-defaults'', ``help'',
and ``bitmap''. The suffix parameter is intended to be appended to the file name. Possible values might include ``.txt'', ``.dat'', and ``.bm''. X Version 11 Last change: libXt 1.0.8 2XT FUNCTIONS XtResolvePathname(3xt)
A suggested value for the default path on POSIX-based sys-
tems is/usr/lib/X11/%L/%T/%N%C%S:/usr/lib/X11/%l/%T/%N%C%S:.br
/usr/lib/X11/%T/%N%C%S:/usr/lib/X11/%L/%T/%N%S:.br
/usr/lib/X11/%l/%T/%N%S:/usr/lib/X11/%T/%N%S
Using this example, if the user has specified a language, itwill be used as a subdirectory of /usr/lib/X11 that will be searched for other files. If the desired file is not found there, the lookup will be tried again using just the language part of the specification. If the file is not
there, it will be looked for in /usr/lib/X11. The type
parameter is used as a subdirectory of the language direc-
tory or of /usr/lib/X11, and suffix is appended to the file name.
The %D substitution allows the addition of path elements to
the implementation-specific default path, typically to allow
additional directories to be searched without preventing resources in the system directories from being found. For example, a user installing resource files under a directory called ``ourdir'' might set XFILESEARCHPATH to%D:ourdir/%T/%N%C:ourdir/%T/%N
The customization string is obtained by querying the resource database currently associated with the display (the database returned by XrmGetDatabase) for the resourceapplication_name.customization, class
application_class.Customization where application_name and
application_class are the values returned by XtGetApplica-
tionNameAndClass. If no value is specified in the database, the empty string is used. It is the responsibility of the caller to free the returned string using XtFree when it is no longer needed.SEE ALSO
