FD_SET - coredump

[liningjie418]

When I use FD_SET , my app core dumped. I notice ff_socket() return fd larger than 1024, is there has any ways ?

do not use select , use epoll

Same issue. Why we need an API(ff_select) that we can't use?

This issue has been fixed in PR #899 (merged 2025-06-11), which adds proper select interface support and ensures ff sockets do not start from fd >= 1024 to avoid FD_SET overflow. Please upgrade to the latest version. Closing this issue.
