Variable number of parameters

[sschilachi]

How do I write a function that has a variable number of parameters. Ideally I would like the first parameter to be an integer, and then that number of parameters must be entered. For example function(5,1,2,3,4,5) or function(3,1,2,3) Thanks

for variable no. of arguments use va_arg, look into MSDN for more details

[toxcct]

return_type fonction (...);

the '...' is the C style to say that th function can have a variable number of parameters. if you want fixed parameters, with a variable list below , do this (printf() function for example):

int printf(const char*, ...);

To access such parameters, use the macros va_start(), va_arg() and va_end(), plus the va_list type.

In this particular case:

int function( int nParams, ... );

and then use va_list:

int function( int nParams, ... )
{
int argValue;

va_list args;
va_start( args, nParams );

for ( int nParam = 0; nParam < nParams; ++nParam )
{
argValue = va_arg( args, int );

  // Do something with argValue

}
}

Stability. What an interesting concept. -- Chris Maunder
