 * Structure for holding a set of file descriptors, similar to fd_set.

 * This structure however can hold so-called large file descriptors
 * (>= FD_SETSIZE or 1024) on Unix systems or more than FD_SETSIZE (64)
 * sockets on Windows systems.
 *
 * It is safe to allocate this structure on the stack.
 *
 * This structure must be initialized by calling netsnmp_large_fd_set_init()
 * and must be cleaned up via netsnmp_large_fd_set_cleanup(). If this last
 * function is not called this may result in a memory leak.
 *
 * The members of this structure are:
 * lfs_setsize: maximum set size.
 * lsf_setptr:  points to lfs_set if lfs_setsize <= FD_SETSIZE, and otherwise
 *              to dynamically allocated memory.
 * lfs_set:     file descriptor / socket set data if lfs_setsize <= FD_SETSIZE.
