How to read the standard input into string variable until EOF in C?

Question

I am getting \"Bus Error\" trying to read stdin into a char* variable. I just want to read whole stuff coming over stdin and put it fi

Since you don't care about the actual content, why bother building a string? I'd also use getchar():

int    c;
size_t s = 0;

while ((c = getchar()) != EOF)
{
  s++;
}

printf("Size: %z\n", s);

This code will correctly handle cases where your file has '\0' characters in it.
