I've tried the sample code of Oracle's documentation. I had to make small changes, since the initial code does not compile... Unfortunately, the final code compiles, but does not work. The OCIString pointer points to a NULL string. Coul you tell me what I'm doing wrong ????
  OCIString     *vstring1 = (OCIString *)0;
  char          c_string[20];
  sword        status;

  strcpy(c_string, "hello world");
  ub4 lg = strlen(c_string);
  /* Assign a text string to an OCIString */
  status = OCIStringAssignText( m_pEnv, m_pErr, (text*) c_string, lg, &vstring1);
  /* Memory for vstring1 is allocated as part of string assignment */
  text* ptr = OCIStringPtr( m_pEnv, vstring1 );

After the call to OCIStringPtr, ptr == NULL.
NB : m_pEnv & m_pErr are allocated & valid
