Pass pointer to char array as parameter to function - C


Macaque

In the function declaration below, the first parameter is a String, specifically an array of chars, and the third parameter is a pointer to an integer. Is the second parameter a pointer to an array of characters? In other words, a pointer to a pointer? I found this after reading the answers to the following question: Difference between passing an array and an array pointer to a function in C

void setup(char inputBuffer[], char *args[], int *background) {...}

In other words, is *args[] equivalent to **args?

thank you very much!

Yes, when passing arguments to functions, the char *args[]equivalent of char **args.

In the first parameter char inputBuffer[], the function does not actually receive the entire array char, but only a pointer variable that holds the address of its first element.

In the second parameter char *args[], similarly, the function does not receive the entire array of pointers to chars , but a pointer variable that holds the address of the first element. In this case, the element itself is a pointer. Therefore, the function receives a charpointer to char **args.
