In C & C++ a function argument defined as an array is the same as if it
was defined as a pointer. That is both are pointers (and not an array).
Consider the code:

unsigned long slen(char p[10])
{
 unsigned long size=0;
 
 while(*p++)
   size++;

 return size;
}


So **argv, *argv[] and argv[][] are the same thing as function arguments
(only). For normal code only the first 2 can be considered compatible.
