LR_LENGTH - obtain length of remaining record.

Usage:

#include <ld.h>
length = lr_length();

Where:

int length;: is the number of bytes remaining in the current record.

Description:

"lr_length" tells how many bytes have not yet been read in the current record. This will always be a positive integer, except for records which are continued by LD_CONTINUATION records. In this case, "lr_length" returns the negative of the number of bytes left in the record, to indicate that the record continues on to a new record.

Note that the correct length is returned for extended records.
