Parameter

Data Type

Description

size

int

Length of the user data. Value range: [0, 64]

offset

int

Offset of the user data, which must comply with the following restriction:

[0, 64), size+offset<=64

Returns

bytearray is returned in normal scenarios.

Examples

import dataflow as df
graph = df.FlowGraph(...)
user_data_str = "UserData123"

flowinfo = result[1]
fetch_user_data = flowinfo.get_user_data(len(user_data_str))
name = fetch_user_data.decode('utf-8')
print(name)
