Selecting multiple rows of variable length data into an array

When multiple rows of a variable length data (VARCHAR or VARBINARY) are selected into a buffer, each new item begins at an index that is a multiple of datafmt->maxlength, even if the preceding item is less than datafmt->maxlength bytes long. This is illustrated in the code fragment below.

/* This example demonstrates selecting multiple rows of
variable-length data into a buffer. In this case, the
first row to be returned will have one column with the
value "first string" and a second row with a column with
the value "second string". */ 
datafmt.count = 2;
datafmt.maxlength = 25;
retcode = ct_results(cmd, &restype);
if (retcode != CS_SUCCEED)
{
		/* error handling code deleted */
		. . .
}
if (restype == CS_ROW_RESULT)
{ 
		retcode = ct_bind(cmd, 1, datafmt, buffer, CS_NULL, CS_NULL);
		if (retcode != CS_SUCCEED)
		{
			/* error handling code deleted */
			. . .
		}
		retcode = ct_fetch(cmd, CS_UNUSED, CS_UNUSED, 
			&nrows);
		if (retcode != CS_SUCCEED)
		{
			/* error handling code deleted */
			. . .
		}

/* At this point, the string "first string" begins at
buffer[0] and the string "second string" begins at
buffer[25], even though the first data item was less
than 25 characters long.*/
