      Detect if connection was closed on remote side

      Hi there. I'm writing a tool, which must detect is connection was terminated on remote side.

      Every action on network, I'm fetching with select(). And I want in some place check if connection still active.

      There are code:

      Code:
      while (1)
  {
    tv.tv_sec = 1;
    tv.tv_usec = 0; 

    FD_ZERO (&readfds);
    FD_SET (priv->socket, &readfds); 
    rc = select
      ...

        send() on non-blocking sockets

        Hi there. I'm developing a tool, which uses non-blocking sockets on Linux.

        When I'm sending something to socket with send(), the return value is -1, which means error. But it's not an error. <errno> indicates that this is EWOULDBLOCK, which means that my request will be async ;-)

        I want to get number of bytes really written to socket, but not -1 as I get now.

        Code:
        switch (errno)
  {
    case
        ...

          Relative path to absolute

          Hi there.

          I'm writing a program under Linux. I need a function that convert relative path to absolute (or full path). Under Windows, I have a GetFullPathName function in WinAPI. But now, I need function for Linux (glibc may be).

          Can someone help me?

          P.S. Googling, googling... nothing found ;-(
