NAME

	ReadChunkRecords -- read record elements from the current chunk into
			    a buffer. (V36)

SYNOPSIS

	actual = ReadChunkRecords(iff, buf, bytesPerRecord, numRecords);
	D0                        A0   A1   D0              D1
	LONG ReadChunkRecords(struct IFFHandle *, APTR, LONG, LONG);

FUNCTION

	Reads records from the current chunk into buffer. Truncates attempts
	to read past end of chunk (only whole records are read; remaining
	bytes that are not of a whole record size are left unread and
	available for ReadChunkBytes()).

INPUTS

	iff - pointer to IFFHandle structure.
	buf - pointer to buffer area to receive data.
	bytesPerRecord	- size of data records to read.
	numRecords - number of data records to read.

RESULT

	actual - (positive) number of whole records read if successful or a
		 (negative) IFFERR_#? error code if unsuccessful.
