SILC_ASN1_NULL

SYNOPSIS

    Encoding:
    SILC_ASN1_NULL
    SILC_ASN1_NULL_T(opts, tag, set)

    Decoding:
    SILC_ASN1_NULL
    SILC_ASN1_NULL_T(opts, tag, &set)

DESCRIPTION

Macro used to encode or decode null value.

The `opts' is SilcAsn1Options. The `tag' is a tag number. In encoding `set' is SilcBool and if it is TRUE the NULL value will be encoded. If it is FALSE the SILC_ASN1_NULL will be ignored. In decoding the `set' is SilcBool and if it is TRUE the NULL value was present. This can be used to verify whether NULL was present if it is SILC_ASN1_OPTIONAL.
