ber_next_element function

The ber_next_element function is used along with ber_first_element to traverse a SET, SET OF, SEQUENCE or SEQUENCE OF data value stored in the supplied BerElement structure. It returns the tag and length of the next element in the constructed type.

Syntax

ULONG ber_next_element(
  _In_    BerElement *pBerElement,
  _Inout_ ULONG      *pLen,
  _Inout_ CHAR       *opaque
);

Parameters

pBerElement [in]

Pointer to the source BerElement structure.

pLen [in, out]

Returns the length of the next element to be parsed.

opaque [in, out]

An opaque cookie used internally that was returned by the initial call to the ber_first_element function.

Return value

Returns the tag of the next element to be read in the BerElement structure. LBER_DEFAULT is returned if there is no further data to be read.

Remarks

The pLen and opaque pointer values returned by the function are internal parsing state values, and should not be used by applications other than as arguments to subsequent calls of this function.
