- The substitutions specified by _X_t_R_e_s_o_l_v_e_P_a_t_h_n_a_m_e are
- determined from the value of the language string retrieved
- by _X_t_D_i_s_p_l_a_y_I_n_i_t_i_a_l_i_z_e for the specified display. To set
- the language for all applications specify ``*xnlLanguage:
- _l_a_n_g'' in the resource database. The format and content
- of the language string are implementation-defined. One
- suggested syntax is to compose the language string of
- three parts; a ``language part'', a ``territory
- part'' and a ``codeset part''. The manner in which this
- composition is accomplished is implementation-defined and
- the Intrinsics make no interpretation of the parts other
- than to use them in substitutions as described below.
-
- _X_t_R_e_s_o_l_v_e_P_a_t_h_n_a_m_e calls _X_t_F_i_n_d_F_i_l_e with the following sub-
- stitutions in addition to any passed by the caller and
- returns the value returned by _X_t_F_i_n_d_F_i_l_e:
-
- %N The value of the _f_i_l_e_n_a_m_e parameter, or the

- application's class name if _f_i_l_e_n_a_m_e is NULL.
-
- %T The value of the _t_y_p_e parameter.
-
- %S The value of the _s_u_f_f_i_x parameter.
-
- %L The language string associated with the specified
- display.
-
- %l The language part of the display's language string.
-
- %t The territory part of the display's language string.
-
- %c The codeset part of the display's language string.
-
- %C The customization string retrieved from the resource
- database associated with _d_i_s_p_l_a_y.
-
- %D The value of the implementation-specific default
- path.
-
- If a path is passed to _X_t_R_e_s_o_l_v_e_P_a_t_h_n_a_m_e, it will be
- passed along to _X_t_F_i_n_d_F_i_l_e. If the _p_a_t_h argument is NULL,
- the value of the _X_F_I_L_E_S_E_A_R_C_H_P_A_T_H environment variable will
- be passed to _X_t_F_i_n_d_F_i_l_e. If _X_F_I_L_E_S_E_A_R_C_H_P_A_T_H is not
- defined, an implementation-specific default path will be
- used which contains at least 6 entries. These entries
- must contain the following substitutions:
-
- 1. %C, %N, %S, %T, %L or%C, %N, %S, %T, %l, %t, %c
- 2. %C, %N, %S, %T, %l
- 3. %C, %N, %S, %T
- 4. %N, %S, %T, %L or %N, %S, %T, %l, %t, %c
- 5. %N, %S, %T, %l
- 6. %N, %S, %T
-
- The order of these six entries within the path must be as
- given above. The order and use of substitutions within a
- given entry is implementation dependent. If the path
- begins with a colon, it will be preceded by %N%S. If the
- path includes two adjacent colons, %%NN%%SS will be inserted
- between them.
-
- The _t_y_p_e parameter is intended to be a category of files,
- usually being translated into a directory in the pathname.
- Possible values might include ``app-defaults'', ``help'',
- and ``bitmap''.
-
- The _s_u_f_f_i_x parameter is intended to be appended to the
- file name. Possible values might include ``.txt'',
- ``.dat'', and ``.bm''.

- tems is

-
- where <XRoot> is replaced by the root of the X11 installa-
- tion tree (/usr/X11R6, for example).
-
- Using this example, if the user has specified a language,
- it will be used as a subdirectory of <XRoot>/lib/X11 that
- will be searched for other files. If the desired file is
- not found there, the lookup will be tried again using just
- the language part of the specification. If the file is
- not there, it will be looked for in <XRoot>/lib/X11. The
- _t_y_p_e parameter is used as a subdirectory of the language
- directory or of <XRoot>/lib/X11, and _s_u_f_f_i_x is appended to
- the file name.
-
- The %D substitution allows the addition of path elements
- to the implementation-specific default path, typically to
- allow additional directories to be searched without pre-
- venting resources in the system directories from being
- found. For example, a user installing resource files
- under a directory called ``ourdir'' might set _X_F_I_L_E_S_E_A_R_C_H_-
- _P_A_T_H to
-
- %D:ourdir/%T/%N%C:ourdir/%T/%N
-
- The customization string is obtained by querying the
- resource database currently associated with the display
- (the database returned by _X_r_m_G_e_t_D_a_t_a_b_a_s_e) for the resource
- _a_p_p_l_i_c_a_t_i_o_n___n_a_m_e.customization, class _a_p_p_l_i_c_a_-
- _t_i_o_n___c_l_a_s_s.Customization where _a_p_p_l_i_c_a_t_i_o_n___n_a_m_e and _a_p_p_l_i_-
- _c_a_t_i_o_n___c_l_a_s_s are the values returned by
- _X_t_G_e_t_A_p_p_l_i_c_a_t_i_o_n_N_a_m_e_A_n_d_C_l_a_s_s. If no value is specified in
- the database, the empty string is used.
-
- It is the responsibility of the caller to free the
- returned string using _X_t_F_r_e_e when it is no longer needed.
