This task is inverse to the task [[Call foreign language function]]. Consider the following [[C]] program:
<lang c>#include <stdio.h>

extern int Query (char * Data, size_t * Length);

int main (int argc, char * argv [])
{
   char     Buffer [1024];
   size_t   Size = sizeof (Buffer);

   if (0 == Query (Buffer, &Size))
   {
      printf ("failed to call Query\n");
   }
   else
   {
      char * Ptr = Buffer;
      while (Size-- > 0) putchar (*Ptr++);
      putchar ('\n');
   }
}</lang>

Implement the missing <code>Query</code> function in your language, and let this C program call it. The function should place the string ''<tt style="margin:0 0.5em">Here am I</tt>'' into the buffer which is passed to it as the parameter <code>Data</code>. The buffer size in bytes is passed as the parameter <code>Length</code>. When there is no room in the buffer, <code>Query</code> shall return 0. Otherwise it overwrites the beginning of <code>Buffer</code>, sets the number of overwritten bytes into <code>Length</code> and returns 1.
