In the following function declaration, the first argument is a String, specifically, an array of chars, and the third argument is a pointer to an integer. Is the second argument a pointer to an array of chars? In other words, a pointer to a pointer? I find this after reading this answer to a related question: Difference between passing array and array pointer into function in C
void setup(char inputBuffer[], char *args[], int *background) {...}
In other words, is *args[] equivalent to **args?
Thanks a lot!
Yes, in passing arguments to a function, char *args[] is equivalent to char **args.
In the first argument, char inputBuffer[], the function actually receives not the whole char array but only a pointer variable holding the address of its first element.
In the second argument, char *args[], similarly, the function receives not the whole array of pointers to chars, but a pointer variable holding the address of the first element. In this case the element is itself a pointer. Therefore the function receives a pointer to a char pointer, equivalent to char **args.
