To catch the response from a `recv` operation into a function, you typically need to define a function that encapsulates the receiving process. The specifics of how you do this can depend on the programming language and networking library you are using. Here's a generic example in Python using the `socket` library:
```python
import socket
def receive_data(sock):
data = sock.recv(1024) # Adjust the buffer size as needed
return data
# Example usage:
client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client_socket.connect(("example.com", 80))
received_data = receive_data(client_socket)
print(received_data.decode("utf-8")) # Assuming the data is in UTF-8 encoding
```
In this example, we define a function `receive_data` that takes a socket as an argument. The `recv` operation is performed within this function, and the received data is returned. You can then call this function whenever you want to receive data and handle the response accordingly.
Keep in mind that this is a simple example, and in a real application, you should handle exceptions, buffer size, and decoding appropriately. The actual implementation may vary depending on your specific use case and the programming language you are using.
