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.

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:
23:00:06S $XAPPLRESDIR/%L/uid/%N/23:00:06S $XAPPLRESDIR/%l/uid/%N/23:00:06S $XAPPLRESDIR/uid/%N/23:00:06S $XAPPLRESDIR/%L/uid/23:00:06S $XAPPLRESDIR/%l/uid/23:00:06S $XAPPLRESDIR/uid/23:00:06S $HOME/uid/23:00:06S $HOME/23:00:06S /usr/lib/X11/%L/uid/%N/23:00:06S /usr/lib/X11/%l/uid/%N/23:00:06S /usr/lib/X11/uid/%N/23:00:06S /usr/lib/X11/%L/uid/23:00:06S /usr/lib/X11/%l/uid/23:00:06S /usr/lib/X11/uid/23:00:06S /usr/include/X11/uid/23:00:06S
If neither UIDPATH
nor XAPPLRESDIR
is set, MRM searches the
following pathnames:
23:00:06S $HOME/%L/uid/%N/23:00:06S $HOME/%l/uid/%N/23:00:06S $HOME/uid/%N/23:00:06S $HOME/%L/uid/23:00:06S $HOME/%l/uid/23:00:06S $HOME/uid/23:00:06S $HOME/23:00:06S /usr/lib/X11/%L/uid/%N/23:00:06S /usr/lib/X11/%l/uid/%N/23:00:06S /usr/lib/X11/uid/%N/23:00:06S /usr/lib/X11/%L/uid/23:00:06S /usr/lib/X11/%l/uid/23:00:06S /usr/lib/X11/uid/23:00:06S /usr/include/X11/uid/23:00:06S
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:
.uil
, and if
no file is found, it is searched again with a NULL suffix.
This function returns one of these status return constants:
