| <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> |
