/*"input_file.c":Operating-system dependant functions to read source files.*/ |
|
/* |
* No matter what the operating system, this module must provide the |
* following services to its callers. |
* |
* input_file_begin() Call once before anything else. |
* |
* input_file_end() Call once after everything else. |
* |
* input_file_buffer_size() Call anytime. Returns largest possible |
* delivery from |
* input_file_give_next_buffer(). |
* |
* input_file_open(name) Call once for each input file. |
* |
* input_file_give_next_buffer(where) Call once to get each new buffer. |
* Return 0: no more chars left in file, |
* the file has already been closed. |
* Otherwise: return a pointer to just |
* after the last character we read |
* into the buffer. |
* If we can only read 0 characters, then |
* end-of-file is faked. |
* |
* input_file_push() Push state, which can be restored |
* later. Does implicit input_file_begin. |
* Returns char * to saved state. |
* |
* input_file_pop (arg) Pops previously saved state. |
* |
* input_file_close () Closes opened file. |
* |
* All errors are reported so caller doesn't have to think |
* about I/O errors. |
