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 (using as_perror) so caller doesn't have to think * about I/O errors. No I/O errors are fatal: an end-of-file may be faked. */ char *input_file_give_next_buffer PARAMS ((char *where)); char *input_file_push PARAMS ((void)); unsigned int input_file_buffer_size PARAMS ((void)); int input_file_is_open PARAMS ((void)); void input_file_begin PARAMS ((void)); void input_file_close PARAMS ((void)); void input_file_end PARAMS ((void)); void input_file_open PARAMS ((char *filename, int pre)); void input_file_pop PARAMS ((char *arg)); /* end of input_file.h */
