ReadNFloats ************************************************************* Parameters: File open text file to read floats from N number of floats to read Buffer pointer to buffer to place floats into Globals: None Operation: This routine reads N floats from the specified text file and places them into Buffer. If Buffer is NULL, a buffer is created and passed back to the caller. If EOF is encountered before any floats can be read, NULL is returned. Return: Pointer to buffer holding floats or NULL if EOF Exceptions: ILLEGALFLOAT History: 6/6/89, DSJ, Created.
