One of Osman, Cinar or Eren presumably - none of which matches "BR"
If you are using the flavour of C sockets described in Chapter 10 of the z/OS Communications Server IP Sockets Application Programming Interface Guide and Reference manual, you are trying to use an unsupported function. If you are not, then the rest of my post does not apply! You should note the "Note" right at the beginning of Chapter 10 that this flavour of sockets support is not to be enhanced further. If you study - carefully since it's all a bit complicated! - the section "Introducing TCP/IP concepts: Socket libraries" in Chapter 1. Introducing TCP/IP concepts, you will find the following sentence: <quote> The native TCP/IP C socket library is not POSIX compliant and it should not be used for new C socket program development. </quote> Long ago - c. 1994 - I used to play with this flavour of sockets programming since it was the only game in town. When I read your post, I did not remember noting SO_RCVTIMEO as a SETSOCKOPT() call option and, indeed, with this flavour of sockets support, it does not exist. You can position your cursor at the beginning of Chapter 10 in a PDF file of the manual, search for SO_RCVTIMEO and you will find the first hit in Chapter 12. Or You can go to the description of the SETSOCKOPT() call and search - in vain - for the SO_RCVTIMEO option under "keywords recognized at the socket level".
