MrmOpenHierarchyPerDisplay(library calMrmOpenHierarchyPerDisplay(library call)NAMEMrmOpenHierarchyPerDisplay — Allocates a hierarchy ID and opens all the
UID files in the hierarchy
SYNOPSIS
#include <Mrm/MrmPublic.h>
Cardinal MrmOpenHierarchyPerDisplay(
Display *display,
MrmCount num_files,
String file_names_list[],
MrmOsOpenParamPtr *ancillary_structures_list,
MrmHierarchy *hierarchy_id);
DESCRIPTIONMrmOpenHierarchyPerDisplay 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 allo‐
cates a hierarchy ID and opens all the UID files in the hierarchy. It
initializes the optimized search lists in the hierarchy. If MrmOpen‐
HierarchyPerDisplay encounters any errors during its execution, any
files that were opened are closed.
The application must call XtAppInitialize before calling MrmOpenHierar‐
chyPerDisplay.
display Specifies the connection to the X server and the value to
pass to XtResolvePathname. For more information on the Dis‐
play 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 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 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 con‐
tain the substitution fields accepted by XtResolvePathname. The sub‐
stitution 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 UID‐
PATH 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 sub‐
stituted 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 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.
