.SH NAME
befs_bt_keylen_index \- Finds start of keylen index in a node
.SH SYNOPSIS
"SYNOPSIS"
.sp
\fB
.sp
u16 * befs_bt_keylen_index  (befs_btree_node * \fInode\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fInode\fB\fR
Pointer to the node structure to find the keylen index within
.SH "DESCRIPTION"
.PP
Returns a pointer to the start of the key length index array
of the B+tree node *\fInode\fR
.PP
``The length of all the keys in the node is added to the size of the
header and then rounded up to a multiple of four to get the beginning
of the key length index'' (p.88, practical filesystem design).
.PP
Except that rounding up to 8 works, and rounding up to 4 doesn't.
