示例#1

文件： cfield.c 项目： pombredanne/cpython

static PyObject *
d_get_sw(void *ptr, Py_ssize_t size)
{
#ifdef WORDS_BIGENDIAN
    return PyFloat_FromDouble(_PyFloat_Unpack8(ptr, 1));
#else
    return PyFloat_FromDouble(_PyFloat_Unpack8(ptr, 0));
#endif
}

示例#2

文件： structmodule.c 项目： JupiterSmalltalk/openqwaq

static PyObject *
unpack_double(const char *p,  /* start of 8-byte string */
              int le)         /* true for little-endian, false for big-endian */

	double x;

	x = _PyFloat_Unpack8((unsigned char *)p, le);
	if (x == -1.0 && PyErr_Occurred())
		return NULL;
	return PyFloat_FromDouble(x);
