* Major API changes: |
| 4 |
|
|
| 5 |
|
- The INTERRUPT() macro has been deprecated, and it will be |
| 6 |
|
removed in a future version. Use __attribute__((interrupt)) |
| 7 |
|
explicitly if this functionality is really needed. |
| 8 |
|
|
| 9 |
|
- The standard IO facilities API has been enhanced |
| 10 |
|
|
| 11 |
|
. The backend functions put and get that are passed to fdevopen() |
| 12 |
|
during the setup of a stream now take the stream itself as an |
| 13 |
|
additional argument. |
| 14 |
|
By defining the macro __STDIO_FDEVOPEN_COMPAT_12 before |
| 15 |
|
including <stdio.h>, an fdevopen() function prototype will be |
| 16 |
|
declared that is backwards-compatible with avr-libc version |
| 17 |
|
1.2 and before. |
| 18 |
|
. It is possible to tie user data to a stream using |
| 19 |
|
fdev_set_udata(), and to retrieve them using fdev_get_udata(). |
| 20 |
|
Together with the additional argument to the backend functions, |
| 21 |
|
these functions can now e.g. keep track of internal user state, |
| 22 |
|
or distinguish two different devices using the same backend |
| 23 |
|
function. |
| 24 |
|
. The get backend function can now return _FDEV_EOF to indicate an |
| 25 |
|
end-of-file condition, in addition to _FDEV_ERR for an error |
| 26 |
|
condition. This will affect the internal state that can be |
| 27 |
|
queried using the standard feof() and ferror() functions. |
| 28 |
|
. A new macro fdev_setup_stream() is provided to setup a |
| 29 |
|
user-supplied stream without the need to call fdevopen(), and thus |
| 30 |
|
without requiring malloc(). A similar macro FDEV_SETUP_STREAM() |
| 31 |
|
exists that can be used to initialized a FILE object. The |
| 32 |
|
floating-point implementations of vfscanf() and vfprintf() now |
| 33 |
|
allocate their conversion buffer on the stack, so they do not need |
| 34 |
|
malloc() anymore either. |
