<h2 class="chapter">6 API Compatibility</h2>
|
||
|
|
|
||
|
|
<p>The goal of this section is to describe some API changes that occurred
|
||
|
|
from one version of MPFR to another, and how to write code that can be compiled
|
||
|
|
and run with older MPFR versions. The minimum MPFR version that is
|
||
|
|
considered here is 2.2.0 (released on 20 September 2005).
|
||
|
|
</p>
|
||
|
|
<p>API changes can only occur between major or minor versions. Thus the
|
||
|
|
patchlevel (the third number in the MPFR version) will be ignored in
|
||
|
|
the following. If a program does not use MPFR internals, changes in
|
||
|
|
the behavior between two versions differing only by the patchlevel
|
||
|
|
should only result from what was regarded as a bug or unspecified behavior.
|
||
|
|
</p>
|
||
|
|
<p>As a general rule, a program written for some MPFR version should work
|
||
|
|
with later versions, possibly except at a new major version, where
|
||
|
|
some features (described as obsolete for some time) can be removed.
|
||
|
|
In such a case, a failure should occur during compilation or linking.
|
||
|
|
If a result becomes incorrect because of such a change, please look
|
||
|
|
at the various changes below (they are minimal, and most software
|
||
|
|
should be unaffected), at the FAQ and at the MPFR web page for your
|
||
|
|
version (a bug could have been introduced and be already fixed);
|
||
|
|
and if the problem is not mentioned, please send us a bug report
|
||
|
|
(see <a href="Reporting-Bugs.html#Reporting-Bugs">Reporting Bugs</a>).
|
||
|
|
</p>
|
||
|
|
<p>However, a program written for the current MPFR version (as documented
|
||
|
|
by this manual) may not necessarily work with previous versions of
|
||
|
|
MPFR. This section should help developers to write portable code.
|
||
|
|
</p>
|
||
|
|
<p>Note: Information given here may be incomplete. API changes are
|
||
|
|
also described in the NEWS file (for each version, instead of being
|
||
|
|
classified like here), together with other changes.
