24 | /* |
| 25 | * No matter what the operating system, this module must provide the | |
| 26 | * following services to its callers. | |
| 27 | * | |
| 28 | * input_file_begin() Call once before anything else. | |
| 29 | * | |
| 30 | * input_file_end() Call once after everything else. | |
| 31 | * | |
| 32 | * input_file_buffer_size() Call anytime. Returns largest possible | |
| 33 | * delivery from | |
| 34 | * input_file_give_next_buffer(). | |
| 35 | * | |
| 36 | * input_file_open(name) Call once for each input file. | |
| 37 | * | |
| 38 | * input_file_give_next_buffer(where) Call once to get each new buffer. | |
| 39 | * Return 0: no more chars left in file, | |
| 40 | * the file has already been closed. | |
| 41 | * Otherwise: return a pointer to just | |
| 42 | * after the last character we read | |
| 43 | * into the buffer. | |
| 44 | * If we can only read 0 characters, then | |
| 45 | * end-of-file is faked. | |
| 46 | * | |
| 47 | * input_file_push() Push state, which can be restored | |
| 48 | * later. Does implicit input_file_begin. | |
| 49 | * Returns char * to saved state. | |
| 50 | * | |
| 51 | * input_file_pop (arg) Pops previously saved state. | |
| 52 | * | |
| 53 | * input_file_close () Closes opened file. | |
| 54 | * | |
| f79d9c1d AM |
55 | * All errors are reported so caller doesn't have to think |
| 56 | * about I/O errors. | |
