- The poll() system call may return -1 with errno set to EAGAIN. I have
- two questions regarding this condition.
-
- First, is there a kernel resource which has run dry which can be
- increased by some tuning parameter to prevent this?
-
- Second, how should software handle this condition? For instance, can
- the software depend on getting a SIGPOLL signal later if poll was unable
- to tell the software what to examine in the first place?
