NAMEMrmOpenHierarchy — Allocates a hierarchy ID and opens all the UID files
in the hierarchy
SYNOPSIS
#include <Mrm/MrmPublic.h>
Cardinal MrmOpenHierarchy(
MrmCount num_files,
String file_names_list[],
MrmOsOpenParamPtr *ancillary_structures_list,
MrmHierarchy *hierarchy_id);
DESCRIPTION
This routine is obsolete and exists for compatibility with previous
releases. It is replaced by MrmOpenHierarchyPerDisplay. MrmOpenHierar‐
chy is identical to MrmOpenHierarchyPerDisplay except that MrmOpenHier‐
archy does not take a display argument.
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 path‐
name or a filename. If a UID file string has a leading slash (/), it
specifies a full pathname, and MRM opens the file as specified. Other‐
wise, the UID file string specifies a filename. In this case, MRM
looks for the file along a search path specified by the UIDPATH envi‐
ronment 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 con‐
tain the substitution fields accepted by XtResolvePathname. The sub‐
stitution field %T is always mapped to uid. The entire path is first
searched with %S mapped to .uid. If no file is found, it is searched
again with %S mapped to NULL.
If no display is set prior to calling this function, the result of this
function's call to XtResolvePathname is undefined.
For example, the following UIDPATH value and MrmOpenHierarchy 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;
MrmOpenHierarchy((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 MrmOpenHierarchy, 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 sub‐
stituted for %L.
After MrmOpenHierarchy 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 ven‐
dor 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 call‐
ing 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
This function returns one of the following status return constants:
MrmSUCCESS
The function executed successfully.
MrmNOT_FOUND
File not found.
MrmFAILURE
The function failed.
