 Posted: Thu Jun 01, 2006 1:45 am Post subject: Socket client ... |
 |
|
Hi!
I'm programming an hombrew that receive data from a program who is on my computer with the SOCKET..
For the Windows program, no problem, I usualy program on Windows..
But, for the PSP, i've never seen samples for create client with the socket...
If someone can give me an example, for using client socket on the PSP, because I will connect my psp, with the SERVER program who is in my computer...
Thank, and sorry for my english. |

There is a simple example included with the psp:
/usr/local/pspdev/psp/sdk/samples/net/simple/
You just use standard unix sockets, the only difference is that you need to connect to the wifi first. |

| If/when you finish your program, could you post it here? I would like to see it. |
