segmentation fault in sockets library of sicstus prologThis is a discussion on segmentation fault in sockets library of sicstus prolog within the PROLOG forums in Programming Languages category; Hi all, I am using the linda library in sicstus prolog for commmunication between processes. The linda server is calling the predicate socket_select/7 which sometimes gives segmentation fault and I could trace the error to this particular line in socket_select/7: prolog:'$select'(ListenSocketsRaw,LReadyRaw, ConnectSocketsRaw,CReadyRaw, ReadStreamsRaw,RReadyRaw, WriteStreamsRaw,WReadyRaw, TimeoutParam, ECODE) I could further find out that ultimately this call is making a system call select but I could not find out what happens in between. Could anyone of you tell how to fix this or where does the control go after you make a call to prolog:'$select'? Thanks, Pragyesh... | ||||||||

Sorry, no help from me. I am not using Linux. I was testing Linda extensively on Windows XP/INTEL, with SICStus 4.04 and 3.12.8 without problems. A.L. |

Do you have any idea what does a call like prolog:'$select' transfer control to? |

Sorry - since I had no problems with Linda, I have never studied its internals... A.L. |
