Simple Array Question

[PapaGLP]

i pass an array into a function like so

void intstuff(int **buffer){

}

i just need to know how to determine the actual size (in bytes) of the buffer, all i can get now is the size of the pointer . . . which is always 4

It is impossible to find out the size of a dynamically allocated array (using new or malloc). sizeof can only find out the size of static arrays like buffer[54]. If it was dynamically allocated there is no way to find out. Your best bet is to add an argument to the function (just an int) to keep track of the size. Well in your case since it is a 2-D array, you would want to pass in 2 ints and that will be your sizes for each dimension.
