free()'n args


I'm not sure if it is possible, but I want to make a function called freeAll (hopefully that is self explanitory) using a va_list, I'm not sure if this is possible, could someone help me out on this, anyway.. my reasoning is I have about 7, or 8.. variables malloc'd, and when an error occurs I have to free them all, but I think it would be easier if I could just do something like ->

freeAll(malloc_one, malloc_two, malloc_three, ...) then having to do ->

free(malloc_one);
free(malloc_two);
free(malloc_three);

I know I should've searched a little longer, and probably hunted the forums, but it's hard to phrase this in a search engine..

Code:
void freeAll(void **ptr, int count){
     int i=0;
     for(i=0;i<count;i++)free(ptr[i]);
}

multi-demensional array? hmm, that could work, but I meant passing each variable.. something like:

Code:
void freeAll(int c, void *q, ...)
{
    va_args args;
    int j;

    va_start(args, q);
    for(j = 0; j < c; ++j)
        free(va_arg(args, char*));
}
