  • Field Details

    • fd

      public int fd
      Input field, must contain a file descriptor returned by a previous open call. A negative value makes this pollfd entry invalid. The poll() system calls ignores invalid pollfd entries.

    • events

      public short events
      Input field, must contain a bitwise combination of POLLIN and POLLOUT.

    • revents

      public short revents
      Output field, contains a bitwise combination of POLLIN, POLLOUT, POLLERR, POLLNVAL and perhaps other less relevant values. Specifies the condition that is fulfilled by the corresponding file descriptor.
