| |
My program had 3 threads:
1. while(1) { sk = accept( ... ) ; insert sk into a socket queue ... }
2. ... select() for ( every in socket queue ) if ( FD_SET( sk, ... ) ) read( sk, buf, len ) ...
3. if ( some condition match on a socket ) close( sk )
Now I accept a new socket, such as sk = 19, In thread 3, I detect a condition, and close(19), then I connect server again, accept() return 19 (Now 19 is a free file slot).
But in thread2, the select() return, and read(19) return -1, errno is "Bad file number". It seem that after select(), thread 2 only know 19 is closed, but don't know a new 19 is open. ( I connect server about 1min after close a previous socket, so select() return 1 min after 19 is closed ).
Can any one help me !
