8 | * This allows for 1024 file descriptors: if NR_OPEN is ever grown | |
9 | * beyond that you'll have to change this too. But 1024 fd's seem to be | |
10 | * enough even for such "real" unices like OSF/1, so hopefully this is | |
11 | * one limit that doesn't have to be changed [again]. | |

13 | * Note that POSIX wants the FD_CLEAR(fd,fdsetp) defines to be in | |

15 | * place for them. Solved by having dummy defines in <sys/time.h>. | |
