| 3833 | 48 NOTE NOTE NOTE: |
| 49 Format == 32 means that the buffer will be C longs, which need not be | |
| 50 32-bit quantities. See the note in select-x.c (x_get_window_property). | |
| 51 | |
| 647 | 52 When converting a Lisp number to C, it is assumed to be of format 16 if |
| 53 it is an integer, and of format 32 if it is a cons of two integers. | |
| 54 | |
| 55 When converting a vector of numbers from Elisp to C, it is assumed to be | |
| 56 of format 16 if every element in the vector is an integer, and is assumed | |
| 57 to be of format 32 if any element is a cons of two integers. | |
| 58 | |
| 59 When converting an object to C, it may be of the form (SYMBOL . <data>) | |
| 60 where SYMBOL is what we should claim that the type is. Format and | |
| 61 representation are as above. | |
| 62 | |
| 63 NOTE: Under Mule, when someone shoves us a string without a type, we | |
| 3025 | 64 set the type to `COMPOUND_TEXT' and automatically convert to Compound |
| 647 | 65 Text. If the string has a type, we assume that the user wants the |
| 66 data sent as-is so we just do "binary" conversion. | |
