Hi, Could somebody tell me how is select() resolved to cygwin_select() eventually? I believe cygwin_select() is the core select() implementation, but to the user it is the POSIX API select() that is exported. I see these lines, _select = cygwin_select SIGFE select = cygwin_select SIGFE in cygwin.din. Not sure what this file is and how is it used exactly? Would appreciate if these doubts can be clarified. -- Br, Vinod -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
