RTIME(3N-BSD)       RISC/os Reference Manual        RTIME(3N-BSD)



NAME
     rtime - get remote time

   Headers
     For -systype svr3:

     #include <bsd/sys/types.h>
     #include <bsd/sys/time.h>
     #include <bsd/netinet/in.h>

     For -systype bsd43:

     #include <sys/types.h>
     #include <sys/time.h>
     #include <netinet/in.h>

   Declarations
     int rtime(addrp, timep, timeout)
     struct sockaddrin *addrp;
     struct timeval *timep;
     struct timeval *timeout;

DESCRIPTION
     rtime() consults the Internet Time Server at the address
     pointed to by addrp and returns the remote time in the
     timeval struct pointed to by timep.  Normally, the UDP pro-
     tocol is used when consulting the Time Server. The timeout
     parameter specifies how long the routine should wait before
     giving up when waiting for a reply.  If timeout is specified
     as NULL, however, the routine will instead use TCP and block
     until a reply is received from the time server.

     The routine returns 0 if it is successful. Otherwise, it
     returns -1 and errno is set to reflect the cause of the
     error.

NOTE
     When these routines are used in a program which is compiled
     in -systype svr3, they are not resolved by libc.a.  See
     intro(3) for more information.
