socket_quickack(3) Library Functions Manual socket_quickack(3) NAME socket_quickack - turn TCP Quick ACK mode on or off SYNTAX #include <libowfat/socket.h> int socket_quickack(int s,int value); DESCRIPTION socket_quickack switches TCP Quick ACK mode on (value=1) or off (value=0). If the platform does not support this functionality, returns -1 and sets errno to ENOPROTOOPT (or ENOSYS if the platform does not define ENOPRO- TOOPT). TCP Quick ACK mode is on by default because the operating system has to as- sume it's an interactive connection. In that case, an ACK will be sent quickly after data came in. If your code handles non-interactive server connections, it may make sense to switch Quick ACK mode off, telling the kernel to delay sending ACKs because the server is going to respond to in- coming requests anyway, so the ACK can be piggy-backed onto that response, saving useless network traffic. Normally socket_quickack returns 0. If anything goes wrong, socket_quickack returns -1, setting errno appropriately. EXAMPLE #include <libowfat/socket.h> int s; char ip[4]; uint16 p; s = socket_tcp4b(); socket_quickack(s); socket_bind4_reuse(s,ip,p); socket_listen(16); SEE ALSO socket_fastopen(3) socket_quickack(3)
