NAMEsocketcall - socket system calls
SYNOPSISint socketcall(int call, unsigned long *args);
DESCRIPTIONsocketcall() is a common kernel entry point for the socket system calls. call determines which socket function to invoke. args points to a block containing the actual arguments, which are passed through to the appropriate call.
CONFORMING TOThis call is specific to Linux, and should not be used in programs intended to be portable.
NOTESOn a few architectures, for example ia64, there is no socketcall() system call; instead socket(2), accept(2), bind(2), and so on really are implemented as separate system calls.
