- The _X_C_r_e_a_t_e_O_C function creates an output context within
- the specified output method.
-
- The base font names argument is mandatory at creation
- time, and the output context will not be created unless it
- is provided. All other output context values can be set
- later.
-
- _X_C_r_e_a_t_e_O_C returns NULL if no output context could be cre-
- ated. NULL can be returned for any of the following rea-
- sons:
-
- +o A required argument was not set.
-
- +o A read-only argument was set.
-
- +o An argument name is not recognized.
-
- +o The output method encountered an output method imple-
- mentation-dependent error.
-
- The _X_D_e_s_t_r_o_y_O_C function destroys the specified output con-
- text.
-
- The _X_S_e_t_O_C_V_a_l_u_e_s function returns NULL if no error

- occurred; otherwise, it returns the name of the first
- argument that could not be set. An argument might not be
- set for any of the following reasons:
-
- +o The argument is read-only.
-
- +o The argument name is not recognized.
-
- +o An implementation-dependent error occurs.
-
- Each value to be set must be an appropriate datum, match-
- ing the data type imposed by the semantics of the argu-
- ment.
-
- The _X_G_e_t_O_C_V_a_l_u_e_s function returns NULL if no error
- occurred; otherwise, it returns the name of the first
- argument that could not be obtained. An argument might
- not be obtained for any of the following reasons:
-
- +o The argument name is not recognized.
-
- +o An implementation-dependent error occurs.
-
- Each argument value following a name must point to a loca-
- tion where the value is to be stored.
-
- The _X_O_M_O_f_O_C function returns the output method associated
- with the specified output context.
