.SH NAME
befs_bt_read_node \- read in btree node and convert to cpu byteorder
.SH SYNOPSIS
"SYNOPSIS"
.sp
\fB
.sp
int befs_bt_read_node  (struct super_block * \fIsb\fB, befs_data_stream * \fIds\fB, befs_btree_node * \fInode\fB, befs_off_t \fInode_off\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIsb\fB\fR
Filesystem superblock
.TP
\fB\fIds\fB\fR
Datastream to read from
.TP
\fB\fInode\fB\fR
Buffer in which to place the btree node
.TP
\fB\fInode_off\fB\fR
Starting offset (in bytes) of the node in \fIds\fR
.SH "DESCRIPTION"
.PP
Calls befs_read_datastream to read in the indicated btree node and
makes sure its header fields are in cpu byteorder, byteswapping if
necessary.
.SH "NOTE"
.PP
node->bh must be NULL when this function called first
time. Don't forget brelse(node->bh) after last call.
.PP
On success, returns BEFS_OK and *\fInode\fR contains the btree node that
starts at \fInode_off\fR, with the node->head fields in cpu byte order.
.PP
On failure, BEFS_ERR is returned.
