MrmOpenHierarchyPerDisplay(3X)	   OSF/Motif	MrmOpenHierarchyPerDisplay(3X)

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

       #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*ancil‐
       lary_structures_list;	  MrmHierarchy	   *hierarchy_id;

       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 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.  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.  Specifies the number of
       files  in  the name list.  Specifies an array of character strings that
       identify the UID files.	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 MrmOsOpen‐
       ParamPtr in MrmPublic.h for more information.  Returns the search hier‐
       archy  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 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 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:	     23:00:06S
		 $XAPPLRESDIR/%L/uid/%N/23:00:06S		    $XAPPLRES‐
       DIR/%l/uid/%N/23:00:06S			 $XAPPLRESDIR/uid/%N/23:00:06S
		 $XAPPLRESDIR/%L/uid/23:00:06S			    $XAPPLRES‐
       DIR/%l/uid/23:00:06S			    $XAPPLRESDIR/uid/23:00:06S
		 $HOME/uid/23:00:06S			       $HOME/23:00:06S

       If  neither  UIDPATH nor XAPPLRESDIR is set, MRM searches the following
       pathnames:	      23:00:06S		     $HOME/%L/uid/%N/23:00:06S
		 $HOME/%l/uid/%N/23:00:06S		$HOME/uid/%N/23:00:06S
		 $HOME/%L/uid/23:00:06S			$HOME/%l/uid/23:00:06S
		 $HOME/uid/23:00:06S			       $HOME/23:00:06S

       These paths are defaults that vendors may change.  For example, a  ven‐
       dor    may    use    different	directories   for   /usr/lib/X11   and

       The following substitutions are used  in	 these	paths:	The  UID  file
       string,	from  the  file_names_list  argument.	The  class name of the
       application.  The display's language string.  The language component of
       the  display's  language	 string.   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.

       This  function  returns one of these status return constants: The func‐
       tion executed successfully.  File not found.  The function failed.
