If it's true for TCP, it's wrong for UDP & RAW: netconn_recv in UDP just fetch a "buf" from recvmbox, that why I have precise "for sendto/recvfrom in UDP" in my answer... But like we have talk in https://savannah.nongnu.org/task/?6683, comment #3, #4, #5, there is some solutions about that... ==================================== Frédéric BERNON HYMATOM SA Chef de projet informatique Microsoft Certified Professional Tél. : +33 (0)4-67-87-61-10 Fax. : +33 (0)4-67-70-85-44 Email : [EMAIL PROTECTED] Web Site : http://www.hymatom.fr ==================================== P Avant d'imprimer, penser à l'environnement -----Message d'origine----- De : [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] De la part de Goldschmidt Simon Envoyé : vendredi 11 mai 2007 08:18 À : Mailing list for lwIP users Objet : RE: RE : [lwip-users] Some Help Needed Please > 3/ I'm agree with Kieran, you can use the same socket to send > and recv (lwIP is not already "thread-safe", but if I think > this is not a problem for sendto/recvfrom in UDP, I'm not so Really? Both netconn_recv() and netconn_send() call api_msg_post() which pends on conn->mbox, and that conn (& mbox) is the same for both threads.
