I am trying to pass a pointer to a 3D array to a function in which I want to access an array element using pointer arithmetic.

Define the array:

const unsigned char TS_list_string[2][2][3] = 
{       
 "abc",   "def", 
 "ghi",   "jkl",  
};

Define the function

void process_ts(const unsigned char *T1)
{
unsigned char dv;

    dv = *(*(*(T1 + 1) + 1) + 2);  <----- Compiler error: "Operand of * must be a pointer
}

Main

int main()      
{                                
const unsigned char  *T1;

   T1 =  &TS_list_string[0][0][0];

   process_ts( T1);
}    

Does anyone know what I am doing wrong?

Does anyone know what I am doing wrong?

Mainly, if it's supposed to be a string, where's the space for the \0 that terminates a string?

Yes, the last dimension should be 4 rather than 3 to store the terminator. But that is not the problem, which you do not address.
