* This allows for 1024 file descriptors: if NR_OPEN is ever grown |
* beyond that you'll have to change this too. But 1024 fd's seem to be |
* enough even for such "real" unices like OSF/1, so hopefully this is |
* one limit that doesn't have to be changed [again]. |
* |
* Note that POSIX wants the FD_CLEAR(fd,fdsetp) defines to be in |
* <sys/time.h> (and thus <linux/time.h>) - but this is a more logical |
* place for them. Solved by having dummy defines in <sys/time.h>. |
