It only works for encoded data without embedded NULL bytes. The variant reads one C variable and stores into two C variables, the first one a pointer to an encoding name string (encoding), the second a pointer to a pointer to a character buffer (**buffer, the buffer used for storing ...
This variant on "s" stores into two C variables, the first one a pointer to a character string, the second one its length. In this case the Python string may contain embedded null bytes. Unicode objects pass back a pointer to the default encoded string version of the object if such a ...
This variant on "s" stores into two C variables, the first one a pointer to a character string, the second one its length. In this case the Python string may contain embedded null bytes. "z" (string orNone) [char *] Like "s", but the Python object may also beNone, in which cas...
For example, in Python, 1 array=bytearray(bytes(random.choice(range(256))* length)) and sometimes we want to pass this byte array to C using the PyArg_ParseTuple function (Python-C Library). We can convert the Python bytearray object to a C char* and its length to Py_ssize_t. Her...
