/***********************************************************************
 * int dataasciigen(listofchars, buffer, size, offset)
 *
 * This function fills buffer with ascii characters.
 * The ascii characters are obtained from listofchars or the CHARS array
 *  if listofchars is NULL.
 * Each char is selected by an index.  The index is the remainder
 *  of count divided by the array size.
 * This method allows more than one process to write to a location
 *  in a file without corrupting it for another process' point of view.
 *
 * The return value will be the number of character written in buffer
 *  (size).
