For example, in C you have the function "printf" which takes a char* string with text, formatters, etc. and then you pass in a comma delimited list of variables for each parameter you provided in the first string. How do you define such a function? How do you make reference to these parameters? I assume there must be some base pointer which can be used to access the various entries?
How to allow unspecified number of parameters in C function?
Use "..."
I don't really get it, but there's some documentation here: http://courses.cs.vt.edu/~cs1704/notes/A...
Reply:Use ellipses in function definition:
void Foo( ... )
then use the following to get arguments:
va_list marker;
int first = va_arg( marker, int );
char* pSecond = va_arg( marker, char* );
...
va_end( marker );
