+**  SM_VSPRINTF -- format data for "output" into a string
+**
+**	Assigned 'str' to a "fake" file pointer. This allows common
+**	o/p formatting function sm_vprintf() to be used.
+**
+**	Parameters:
+**		str -- location for output
+**		fmt -- format directives
+**		ap -- data unit vectors for use by 'fmt'
+**
+**	Results:
+**		result from sm_io_vfprintf()
+**
+**	Side Effects:
+**		Quietly limits the size to INT_MAX though this may
+**		not prevent SEGV's.
