50 NOTE NOTE NOTE:
|
|
|
51 Format == 32 means that the buffer will be C longs, which need not be
|
|
|
52 32-bit quantities. See the note in select-x.c (x_get_window_property).
|
|
|

|
54 When converting a Lisp number to C, it is assumed to be of format 16 if
|
|
|
55 it is an integer, and of format 32 if it is a cons of two integers.
|
|
|
56
|
|
|
57 When converting a vector of numbers from Elisp to C, it is assumed to be
|
|
|
58 of format 16 if every element in the vector is an integer, and is assumed
|
|
|
59 to be of format 32 if any element is a cons of two integers.
|
|
|
60
|
|
|
61 When converting an object to C, it may be of the form (SYMBOL . <data>)
|
|
|
62 where SYMBOL is what we should claim that the type is. Format and
|
|
|
63 representation are as above.
|
|
|
64
|
|
|
65 NOTE: Under Mule, when someone shoves us a string without a type, we
|
|
3025
|
66 set the type to `COMPOUND_TEXT' and automatically convert to Compound
|
|
647
|
67 Text. If the string has a type, we assume that the user wants the
|
|
|
68 data sent as-is so we just do "binary" conversion.
