How can I return a character array from a function in C?

Question

is that even possible? Let\'s say that I want to return an array of two characters

char arr[2];
arr[0] = \'c\';
arr[1] = \'a\';

from a func

Answer 1

This works perfecly:

int comm_read_data(int file_i2c, unsigned char** buffer)
{
    *buffer = malloc(BUFFER_SIZE);
    if (i2c_read_bytes(file_i2c, *buffer, BUFFER_SIZE) != 0)
    {
        return -1;
    }
    return BUFFER_SIZE;
}

And then call the function:

unsigned char* buffer;
int length = comm_read_data(file_i2c, &buffer);

/* parse the buffer here */

free(buffer);
