title: expected identifier or ‘(’ before ‘=’ token
body: <p>I'm having trouble with this line:</p>
  
  <p><code>ut_slot = malloc(tab_size * sizeof ut_slot_t);</code></p>
  
  <p>These are the variables which are defined in the header file:</p>
  
  <p><code>typedef struct _ut_slot {
  ...
  ...
  } ut_slot_t, *ut_slot;</code></p>
  
  <p>error is written in title, any help?</p>
