示例#1

文件： cfield.c 项目： pombredanne/cpython

static PyObject *
f_get_sw(void *ptr, Py_ssize_t size)
{
#ifdef WORDS_BIGENDIAN
    return PyFloat_FromDouble(_PyFloat_Unpack4(ptr, 1));
#else
    return PyFloat_FromDouble(_PyFloat_Unpack4(ptr, 0));
#endif
}

示例#2

文件： structmodule.c 项目： JupiterSmalltalk/openqwaq

static PyObject *
unpack_float(const char *p,  /* start of 4-byte string */
             int le)	     /* true for little-endian, false for big-endian */
{
	double x;

	x = _PyFloat_Unpack4((unsigned char *)p, le);
	if (x == -1.0 && PyErr_Occurred())
		return NULL;
	return PyFloat_FromDouble(x);
