binutils-gdb/gas/input-file.h
Ken Raeburn 6efd877de5 Ran "indent", for GNU coding style; some code & comments still need fixup.
Removed some unneeded files.

configure.in: Don't look for te-386bsd.h, which doesn't exist...

/*"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 (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.
