NAME

       MrmOpenHierarchyPerDisplay  —  Allocates a hierarchy ID and opens all the UID files in the
       hierarchy "MrmOpenHierarchyPer\%Display" "uil functions" "MrmOpenHierarchyPer\%Display"

SYNOPSIS

       #include <Mrm/MrmPublic.h>
       Cardinal MrmOpenHierarchyPerDisplay(
       Display *display,
       MrmCount num_files,
       String file_names_list[],
       MrmOsOpenParamPtr *ancillary_structures_list,
       MrmHierarchy *hierarchy_id);

DESCRIPTION

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.

display 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.

num_files Specifies the number of files in the name list.

file_names_list
Specifies an array of character strings that identify the UID files.

ancillary_structures_list
A list of operating-system-dependent ancillary structures corresponding to items
such as filenames, clobber flags, and so forth. This argument should be NULL
for most operations. If you need to reference this structure, see the
definition of MrmOsOpenParamPtr in the MrmPublic.h header file for more
information.

hierarchy_id
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 searched first with %S mapped to
.uid. If no file is found, it 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:

%U The UID file string, from the file_names_list argument.

%N The class name of the application.

%L The display's language string. This string is influenced by XtSetLanguageProc.
The default string is determined by calling setlocale(LC_ALL, NULL).

%l The language component of the display's language string.

%S The suffix to the filename. The entire path is first searched with a suffix of
.uid. If no file is found, it is searched again with a NULL suffix.

RETURN
