Provided by: libmotif-dev_2.3.8-3.1build1_amd64

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

       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.

       MrmCloseHierarchy(3).

                                                                                   MrmOpenHierarchyPerDisplay(3)
