h> library header provides you with routines that are usually implemented as macros to help with this, but they look and operate like functions, so I ll discuss them as though they were You need to use three of these when implementing your own function with a variable number of arguments They are called va_start(), va_arg(), and va_end() The first of these has the following form: void va_start(va_list parg, last_fixed_arg); The name, va_start, is obtained from variable argument start This function accepts two arguments: a pointer parg of type va_list, and the name of the last fixed parameter that you specified for the function you re writing The va_list type is a type that is also defined in <stdargh> and is designed to store information required by the routines provided that support variable argument lists.

So using the function average() as an illustration, you can start to write the function as follows: double average(double v1, double v2,..) { va_list parg; /* Pointer for variable argument list */ /* More code to go here.. */ va_start( parg, v2); /* More code to go her */ }.

By now, you should understand why both statements failed. This example proves that even when the first statement fails the second is executed (and in this case failed with error number 547), which our original example, where the error code was 0 when there were no rows to delete, didn t necessarily prove since the error number there may have come from the

While going into detailed discussion of network ports is outside the scope of this material, there are a few key points to keep in mind. If you choose to bind to ports lower than 1024 on a UNIX/Linux system, you must be root. These ports are known as privileged ports. When using ports above 1024, you have free rein with the only caveat being you cannot use a port that is already in use. There are several methods available for determining whether ports are in use. lsof and netstat normally ship with UNIX and Linux distributions; however, to get the most accurate information, root access is normally required, and the output can vary depending on system type. For an easy method of determining what ports are open, the netstat command can be used. The following portion of code shows me which ports are open on the remote server named www.
