4227 Optional NOERROR, if non-nil, causes require to return nil rather than signal | |
4228 `file-error' if loading the library fails. | |
4229 | |
4230 If feature FEATURE is present in `features', update `load-history' to reflect | |
4231 the require and return FEATURE. Otherwise, try to load it from a library. | |
4232 The normal messages at start and end of loading are suppressed. | |
4233 If the library is successfully loaded and it calls `(provide FEATURE)', add | |
4234 FEATURE to `features', update `load-history' and return FEATURE. | |
4235 If the load succeeds but FEATURE is not provided by the library, signal | |
4236 `invalid-state'. | |
4237 | |
4238 The byte-compiler treats top-level calls to `require' specially, by evaluating | |
4239 them at compile time (and then compiling them normally). Thus a library may | |
4240 request that definitions that should be inlined such as macros and defsubsts | |
4241 be loaded into its compilation environment. Achieving this in other contexts | |
4242 requires an explicit \(eval-and-compile ...\) block. | |
