dynamic function input

[Greber]

Hallo,

I want to create a function, which has a dynamic input like: int FUNCTION (int input, ...)

But in my function I need the input like this way: int FUNCTION (int input1, int input2, int input3, and_so_on...)
I need to call all inputs with local variables.

Is there a possibility? a example?

thx
Florian

sorry, I've forgotten:

how do this "..." exactly work in the function input??

thx Florian

Seems that what you are looking for is a function that accepts a variable number of parameters. This can be accomplished with the use of va_start and other related macros.
For a sample function that uses them you can look at this post

You can find some discussion about the va_xx macrosin these links:

Something like that ?
Regards,


int MyFunction(unsigned short int numberOfArguments,...)
//1) Assumes that all arguments are integers
//2) Assumes that you know the number of arguments when calling the function
{
unsigned short int i;
va_list ap;

if (numberOfArguments <1) return -1; //At least 1 arg.

va_start(ap,numberOfArguments);

for (i=0;i {
int input;
input = va_arg(ap,int);
printf("Arg[%d]: %d\n",i+1,input);
}

va_end(ap);

return(0);
}

is the for-loop realy correct? because of the parameter list

[dilution]

Of course no.
Some characters were lost in the reply
for (i=0;iis the correct loop.

[dilution]

OK. Loop does not want to display properly.
Complete with:
i

Looks like some math symbols do not display.
Complete yoursef with i less than numberOfArguments
and next i.
Regards.
