MrmOpenHierarchyPerDisplay(3X)


OSF/Motif


NAME

  MrmOpenHierarchyPerDisplay - Allocates a hierarchy ID and opens all the UID
  files in the hierarchy


SYNOPSIS

  #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;


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 such things as filenames, clobber flag, and so forth. This argument
      should be NULL for most operations. If you need to reference this
      structure, see the definition of MrmOsOpenParamPtr in <MrmPublic.h> 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 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:

	       %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.

  %l  The language component of the display's language string.

  %S  The suffix to the file name. The entire path is searched first with a
      suffix of .uil, and if no file is found, it is searched again with a
      NULL suffix.


RETURN VALUES

  This function returns one of these status return constants:

  MrmSUCCESS
      The function executed successfully.

  MrmNOT_FOUND
      File not found.

  MrmFAILURE
      The function failed.
