MrmOpenHierarchy(3X)					  MrmOpenHierarchy(3X)

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

       #include <Mrm/MrmPublic.h>

       Cardinal MrmOpenHierarchy(num_files, file_names_list,  ancillary_struc‐
       tures_list, hierarchy_id)
	       MrmCount num_files;
	       String file_names_list[];
	       MrmOsOpenParamPtr *ancillary_structures_list;
	       MrmHierarchy *hierarchy_id;

       This  routine  is  obsolete  and exists for compatibility with previous
       releases.  It is replaced by MrmOpenHierarchyPerDisplay. MrmOpenHierar‐
       chy is identical to MrmOpenHierarchyPerDisplay except that MrmOpenHier‐
       archy does not take a display argument.	Specifies the number of	 files
       in  the	name list.  Specifies an array of character strings that iden‐
       tify 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 MrmOsOpenParamPtr in
       <MrmPublic.h> for more information.  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 substi‐
       tution  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.

       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:

	 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 sub‐
       stituted 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

       If UIDPATH is not set but the environment variable XAPPLRESDIR is  set,
       MRM searches the following pathnames:

       If  neither  UIDPATH nor XAPPLRESDIR is set, MRM searches the following

       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: 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.
