+encoding and decoding.
+.BR ber_alloc_t ()
+is used to create an empty BerElement structure. If
+.B LBER_USE_DER
+is specified for the
+.I options
+parameter then data lengths for data written to the BerElement will be
+encoded in the minimal number of octets required, otherwise they will
+always be written as four byte values. 
+.BR ber_init ()
+creates a BerElement structure that is initialized with a copy of the
+data in its
+.I bv
+parameter.
+.BR ber_init2 ()
+initializes an existing BerElement
+.I ber
+using the data in the
+.I bv
+parameter. The data is referenced directly, not copied. The
+.I options
+parameter is the same as for
+.BR ber_alloc_t ().
 .BR ber_free ()
 frees a BerElement pointed to by \fIber\fP.  If \fIber\fP is NULL, the routine
 does nothing.  If \fIfreebuf\fP is zero, the internal buffer is not freed.
