.SH DESCRIPTION
The
.BR libsimple_strrneqlen ()
function scans the number of bytes the string
.IR a ,
truncated to
.I n
bytes unless it is shorter,
have in common the string
.IR b ,
truncated to
.I n
bytes unless it is shorter,
at their ends.
.PP
The comparison is case-sensitive.

The
.BR libsimple_strrneqlen ()
function returns the number of bytes
.I a
and
.I b
(both truncated to
.I n
bytes) have in common at their ends.
