Can you tell me why ? Thank you !
$ cc -L /usr/lib server.c -lsocket
UX:acomp: WARNING: "server.c", line 60: argument is incompatible with prototype6
Undefined first referenced
symbol in file
ffush server.o
UX:ld: ERROR: a.out: fatal error: Symbol referencing errors. No output written t
$

It could be these possible errors :
Assumption :- ( U r writing Server Module Using Sockets)
1) bind , accepts SSC functions requires one of the parameters as a pointer to struct sockaddr structure. Kindly be sure u r using a structure of said type or else u have to typecast it.

2) I think u r trying to use fflush instead of ffush.

Try these points , u might get ur code sucessfully compiled
