Hello List, I just need some guidance here. I have a parent process fork off a child and pass the int value to the child indicating what the native socket file descriptor it should use to receive communication from the parent process. I am just not able to get it placed back into a boost::asio::local::stream_protocol::socket object. Here is the code below, from the child process loaded via execlp: for(int i = 3; i < static_cast<unsigned char>(~0); i++) { if(i == boost::lexical_cast<int>(argv[0])) { continue; } close(i); } boost::asio::io_service io_service; boost::asio::local::stream_protocol::socket parent_(io_service); parent_.assign(boost::asio::local::stream_protocol, boost::lexical_cast<int>(argv[0])); Compiler error: g++ -c -g -MMD -MP -MF build/Debug/GNU-Linux-x86/main.o.d -o build/Debug/GNU-Linux-x86/main.o main.cpp main.cpp: In function ‘int main(int, char**)’: main.cpp:30: error: expected primary-expression before ‘,’ token Thank you, Etienne -- This message has been scanned for viruses and dangerous content by Pinpoint, and is believed to be clean.
