Re: [PROGRAMMERING] UDP sockets i linux

Tak for det. Programmerne var meget behjælpelige, men hvordan ville du gøre det med PF_LOCAL og AF_UNIX?

Jeg har et problem, da jeg gerne vil bruge en udp socket (AF_UNIX; DGRAM) til to-vejs kommunikation, men for at kunne modtage data, skal bind() kaldes, og den kan ikke kaldes mere end én gang på den samme socketpath.

Nogen der har en løsning?


Jeg har skrevet et par små-programmer til dig.


http://www.hswn.dk/~henrik/udpsockets/socksrv.c er en UDP server.
http://www.hswn.dk/~henrik/udpsockets/sockclient.c er en UDP klient.
Oversættes med "gcc -o socksrv socksrv.c; gcc -o sockclient sockclient.c"

De kan snakke med hinanden. Klienten prompter for en tekst; den sender teksten til serveren som behandler den og sender svar tilbage til klienten. 

    $ ./sockclient 127.0.0.1 1923
    Enter message: Dav
    Waiting for response ...
    Got message:
    vaD
    Enter message: Hej med dig
    Waiting for response ...
    Got message:
    gid dem jeH

og i et andet vindue: 

    $ ./socksrv 127.0.0.1 1923
    Got message: Dav

Got message: Hej med dig


Henrik
