NAME¶
MrmOpenHierarchy — Allocates a hierarchy ID and opens all the UID
files in the hierarchy "MrmOpenHierarchy" "uil functions"
"MrmOpenHierarchy"
SYNOPSIS¶
#include <Mrm/MrmPublic.h>
Cardinal MrmOpenHierarchy(
MrmCount num_files,
String file_names_list[],
MrmOsOpenParamPtr *ancillary_structures_list,
MrmHierarchy *hierarchy_id);
"MRM function" "MrmOpenHierarchy"
"MrmOpenHierarchy" "definition"
DESCRIPTION¶
This routine is obsolete and exists for compatibility with previous releases. It
is replaced by
MrmOpenHierarchyPerDisplay.
MrmOpenHierarchy is
identical to
MrmOpenHierarchyPerDisplay except that
MrmOpenHierarchy 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
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. 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 substituted 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 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¶
This function returns one of the following status return constants:
"MrmSUCCESS" "MrmNOT_FOUND" "MrmFAILURE"
- MrmSUCCESS
- The function executed successfully.
- MrmNOT_FOUND
- File not found.
- MrmFAILURE
- The function failed.
MrmOpenHierarchyPerDisplay(3) and
MrmCloseHierarchy(3).
