| + | ===== - python端发送bytes数据到c ===== | ||
| + | |||
| 通过python发一组数据到C，C调用底层硬件完成数据收尾操作，数据主要是char *的形式到c，python这边需要使用bytes对其相连。 | 通过python发一组数据到C，C调用底层硬件完成数据收尾操作，数据主要是char *的形式到c，python这边需要使用bytes对其相连。 | ||

| + | PyObject* PyBytes_FromStringAndSize(const char *v, Py_ssize_t len) | ||
| + | //Return value: New reference. | ||
| + | //Return a new bytes object with a copy of the string v as value and length len on success, and NULL on failure. If v is NULL, the contents of the bytes object are uninitialized. | ||
| + | |||
| + | |||
| + | |||
| + | PyObject* PyByteArray_FromStringAndSize(const char *string, Py_ssize_t len) | ||
| + | //Return value: New reference. | ||
| + | //Create a new bytearray object from string and its length, len. On failure, NULL is returned. | ||
| + | |||
| + | |||
| + | |||
| + | PyObject* PyUnicode_FromStringAndSize(const char *u, Py_ssize_t size) | ||
| + | //Return value: New reference. | ||
| + | //Create a Unicode object from the char buffer u. The bytes will be interpreted as being UTF-8 encoded. The buffer is copied into the new object. If the buffer is not NULL, the return value might be a shared object, i.e. modification of the data is not allowed. | ||
| + | |||
| + | //If u is NULL, this function behaves like PyUnicode_FromUnicode() with the buffer set to NULL. This usage is deprecated in favor of PyUnicode_New(). | ||
