1505			The function 'name' is only referenced in the translation unit where it is defined.
	CMA maintenance checks

This object / function is only used in the same translation unit where it is defined. As this function is not used outside of this translation unit, it would be better practice to reduce its visibility by declaring it static in C or moving it into an unnamed namespace in C++.

// TU1.cpp
int sort ()
{
  // implement sort specific to TU1
}

void foo()
{
  sort ();
}

// TU2.cpp
void bar()
{
}

// TU1.cpp
int sort ()
{
  // implement sort specific to TU1
}

void foo()
{
  sort ();
}

// TU2.cpp
int sort (); // typo here.  'S' not 's' in sort.

void bar()
{
  sort ();
}

// TU1.cpp
static int sort ()
{
  // implement sort specific to TU1
}

void foo()
{
  sort ();
}

// TU2.cpp
int sort (); // typo here.  'S' not 's' in sort.

void bar()
{
  sort ();   // OK:        Causes link error, 'sort' is not defined
}
