<h2><a name="introduction" id=

"introduction"></a>Introduction</h2>
|
|
|
|
<p>Python 2.5 introduces a new <tt>Py_ssize_t</tt> typedef and
|
|
two related macros (<a href=
|
|
"http://www.python.org/dev/peps/pep-0353/">PEP 353</a>). The
|
|
<tt><boost/python/ssize_t.hpp></tt> header imports these
|
|
definitions into the <tt>boost::python</tt> namespace as
|
|
<tt>ssize_t</tt>, <tt>ssize_t_max</tt>, and <tt>ssize_t_min</tt>.
|
|
Appropriate definitions are provided for backward compatibility
|
|
with previous Python versions.</p>
|
|
|
|
<h2><a name="typedefs" id="typedefs"></a>Typedefs</h2>Imports
|
|
<tt>Py_ssize_t</tt> into the <tt>boost::python</tt> namespace if
|
|
available, or provides an appropriate typedef for backward
|
|
compatibility:
|
|
<pre>
|
|
#if PY_VERSION_HEX >= 0x02050000
|
|
typedef Py_ssize_t ssize_t;
|
|
#else
|
|
typedef int ssize_t;
|
|
#endif
|
|
</pre>
|
|
|
|
<h2><a name="constants" id="constants"></a>Constants</h2>Imports
|
|
<tt>PY_SSIZE_T_MAX</tt> and <tt>PY_SSIZE_T_MIN</tt> as constants
|
|
into the <tt>boost::python</tt> namespace if available, or
|
|
provides appropriate constants for backward compatibility:
|
|
<pre>
|
|
#if PY_VERSION_HEX >= 0x02050000
|
|
ssize_t const ssize_t_max = PY_SSIZE_T_MAX;
|
|
ssize_t const ssize_t_min = PY_SSIZE_T_MIN;
|
|
#else
|
|
ssize_t const ssize_t_max = INT_MAX;
|
|
ssize_t const ssize_t_min = INT_MIN;
|
|
#endif
|
|
</pre>
