How do you declare and call a function with a variable number of parameters in C? I'm assuming that this would be similar to C++ function overloading, but I can't seem to find a complete description. I've seen some mentioning of using ... or > in the declaration, but nothing that really helps. Anyone got any suggestions?
A variable number of parameters, or actual overloaded functions?
a) variable number of parameters:
void myfunction( int x, ... );
/* ... means variable parameters */
b) actual overloaded functions
void myfun( int x );
void myfun( float f );
You cannot have overloading in C.
You can have variable parameters though, as per the definition of
printf.
The thing about variable parameters is that you have to have some way of telling your function what parameters are actually there. This is what printf does with it's % tags in the first format.
Quzah.
Hope is the first step on the road to disappointment.
