MrmOpenHierarchyPerDisplay - Allocates a hierarchy ID and
opens all the UID files in the hierarchy
#include <Mrm/MrmPublic.h>
Cardinal MrmOpenHierarchyPerDisplay (display, num_files,
file_names_list, ancillary_structures_list, hierarchy_id)
Display *display;
MrmCount num_files;
String file_names_list[];
MrmOsOpenParamPtr *ancillary_structures_list;
MrmHierarchy *hierarchy_id;
MrmOpenHierarchyPerDisplay allows you to specify the list
of UID files that MRM searches in subsequent fetch operations.
All subsequent fetch operations return the first
occurrence of the named item encountered while traversing
the UID hierarchy from the first list element (UID file
specification) to the last list element. This function
also allocates a hierarchy ID and opens all the UID files
in the hierarchy. It initializes the optimized search
lists in the hierarchy. If MrmOpenHierarchyPerDisplay
encounters any errors during its execution, any files that
were opened are closed.
The application must call XtAppInitialize before calling
MrmOpenHierarchyPerDisplay. Specifies the connection to
the X server and the value to pass to XtResolvePathname.
For more information on the Display structure, see the
Xlib function XOpenDisplay. Specifies the number of files
in the name list. Specifies an array of character strings
that identify the UID files. A list of operating-systemdependent
ancillary structures corresponding to such
things as filenames, clobber flag, and so forth. This
argument should be NULL for most operations. If you need
to reference this structure, see the definition of
MrmOsOpenParamPtr in <MrmPublic.h> for more information.
Returns the search hierarchy ID. The search hierarchy ID
identifies the list of UID files that MRM searches (in
order) when performing subsequent fetch calls.
Each UID file string in file_names_list can specify either
a full pathname or a filename. If a UID file string has a
leading slash (/), it specifies a full pathname, and MRM
opens the file as specified. Otherwise, the UID file
string specifies a filename. In this case MRM looks for
the file along a search path specified by the UIDPATH
environment variable or by a default search path, which
varies depending on whether or not the XAPPLRESDIR environment
variable is set.
The UIDPATH environment variable specifies a search path
and naming conventions associated with UID files. It can
contain the substitution field %U, where the UID file
string from the file_names_list argument to MrmOpenHierarchyPerDisplay
is substituted for %U. It can also contain
the substitution fields accepted by XtResolvePathname. The
substitution field %T is always mapped to uid. The entire
path is first searched with %S mapped to .uid and then, if
no file is found, is searched again with %S mapped to
NULL. For example, the following UIDPATH value and
MrmOpenHierarchyPerDisplay call cause MRM to open two separate
UID files:
UIDPATH=/uidlib/%L/%U.uid:/uidlib/%U/%L
static char *uid_files[] = {"/usr/users/me/test.uid",
"test2"};
MrmHierarchy *Hierarchy_id;
MrmOpenHierarchyPerDisplay((MrmCount)2,uid_files, NULL,
Hierarchy_id)
MRM opens the first file, /usr/users/me/test.uid, as specified
in the file_names_list argument to MrmOpenHierarchyPerDisplay,
because the UID file string in the
file_names_list argument specifies a full pathname. MRM
looks for the second file, test2, first as
/uidlib/%L/test2.uid and second as /uidlib/test2/%L, where
the display's language string is substituted for %L.
After MrmOpenHierarchyPerDisplay opens the UID hierarchy,
you should not delete or modify the UID files until you
close the UID hierarchy by calling MrmCloseHierarchy.
If UIDPATH is not set but the environment variable XAPPLRESDIR
is set, MRM searches the following pathnames:
%U%S
$XAPPLRESDIR/%L/uid/%N/%U%S
$XAPPLRESDIR/%l/uid/%N/%U%S
$XAPPLRESDIR/uid/%N/%U%S
$XAPPLRESDIR/%L/uid/%U%S
$XAPPLRESDIR/%l/uid/%U%S
$XAPPLRESDIR/uid/%U%S
$HOME/uid/%U%S
$HOME/%U%S
/usr/lib/X11/%L/uid/%N/%U%S
/usr/lib/X11/%l/uid/%N/%U%S
/usr/lib/X11/uid/%N/%U%S
/usr/lib/X11/%L/uid/%U%S
/usr/lib/X11/%l/uid/%U%S
/usr/lib/X11/uid/%U%S
/usr/include/X11/uid/%U%S
If neither UIDPATH nor XAPPLRESDIR is set, MRM searches
the following pathnames:
%U%S
$HOME/%L/uid/%N/%U%S
$HOME/%l/uid/%N/%U%S
$HOME/uid/%N/%U%S
$HOME/%L/uid/%U%S
$HOME/%l/uid/%U%S
$HOME/uid/%U%S
$HOME/%U%S
/usr/lib/X11/%L/uid/%N/%U%S
/usr/lib/X11/%l/uid/%N/%U%S
/usr/lib/X11/uid/%N/%U%S
/usr/lib/X11/%L/uid/%U%S
/usr/lib/X11/%l/uid/%U%S
/usr/lib/X11/uid/%U%S
/usr/include/X11/uid/%U%S
These paths are defaults that vendors may change. For
example, a vendor may use different directories for
/usr/lib/X11 and /usr/include/X11.
The following substitutions are used in these paths: The
UID file string, from the file_names_list argument. The
class name of the application. The display's language
string. The language component of the display's language
string. The suffix to the file name. The entire path is
searched first with a suffix of .uil, and if no file is
found, it is searched again with a NULL suffix.
This function returns one of these status return constants:
The function executed successfully. File not
found. The function failed.
