[section boost/python/ssize_t.hpp]
[section Introduction]
Python 2.5 introduces a new `Py_ssize_t` typedef and two related macros ([@http://www.python.org/dev/peps/pep-0353/ PEP 353]). The <boost/python/ssize_t.hpp> header imports these definitions into the `boost::python` namespace as `ssize_t`, `ssize_t_max`, and `ssize_t_min`. Appropriate definitions are provided for backward compatibility with previous Python versions.
[endsect]
[section Typedefs]
Imports `Py_ssize_t` into the `boost::python` namespace if available, or provides an appropriate typedef for backward compatibility:
``
#if PY_VERSION_HEX >= 0x02050000
typedef Py_ssize_t ssize_t;
#else
typedef int ssize_t;
#endif
``
[endsect]
[section Constants]
Imports `PY_SSIZE_T_MAX` and `PY_SSIZE_T_MIN` as constants into the `boost::python` namespace if available, or provides appropriate constants for backward compatibility:
``
#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
