dfindl - find last active record in RMSfile
#include
rno_t dfindl (buffer, fcb)
char *buffer;
DFILE *fcb;
Dfindl finds the last active record in an opened RMSfile.
Fcb is the file block pointer returned by dlopen(C-3)
or
dopen(C-3).
The returned record number may be saved and used on a subsequent
call to dread(C-3). The record found
is returned in buffer.

Chapter 4, RMS Programming Guide
Dfindl returns a value of BAD (-1) if there is no active record
or if an I/O error occurred. If no record is found, the contents
of buffer are undefined.
