| 39 * Each dynamically loaded Emacs module is given a name at compile | |
| 40 * time. This is a short name, and must be a valid part of a C | |
| 41 * identifier. This name is used to construct the name of several | |
| 42 * functions which must appear in the module source code. | |
| 43 * The first such function, modules_of_XXXX, should load in any dependent | |
| 44 * modules. This function is optional, and the module will still load if | |
| 45 * it is not present in the module. | |
| 46 * | |
| 47 * The second function, which is NOT optional, is syms_of_XXXX, in which | |
| 48 * all functions that the module will be provided are declared. This | |
| 49 * function will contain calls to DEFSUBR(). | |
| 50 * | |
| 51 * The third function, which is also NOT optional, is vars_of_XXXX, in | |
| 52 * which you declare all variables that the module provides. This | |
| 53 * function will contain calls to DEFVAR_LISP(), DEFVAR_BOOL() etc. | |
| 54 * | |
| 55 * When declaring functions and variables in the syms_of_XXXX and | |
| 56 * vars_of_XXXX functions, you use the exact same syntax that you | |
| 57 * would as if this module were being compiled into the pure Emacs. | |
| 58 * | |
| 59 * The fourth function, which is optional, is unload_XXXX, in which actions | |
| 60 * that must be taken to unload the module are listed. XEmacs will unbind | |
| 61 * functions and variables for you. Anything else that must be done should | |
| 62 * appear in this function. | |
| 63 * | |
| 64 * All four of these functions are declared as void functions, | |
| 65 * taking no parameters. Since this sample module is called 'sample', | |
| 66 * the functions will be named 'modules_of_sample', 'syms_of_sample', | |
| 67 * 'vars_of_sample', and 'unload_sample'. | |
