[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.

[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
