EV_SELECT_USE_FD_SET

If defined to 1, then the select backend will use the system fd_set
|

structure. This is useful if libev doesn't compile due to a missing
|

NFDBITS or fd_mask definition or it misguesses the bitset layout on
|

exotic systems. This usually limits the range of file descriptors
|

to some low limit such as 1024 or might have other limitations

(winsocket only allows 64 sockets). The FD_SETSIZE macro, set
|
||||
before compilation, might influence the size of the fd_set used.
