AsnAny

The AsnAny structure contains an SNMP variable type and value. This structure is a member of the RFC1157VarBind structure that is used as a parameter in many of the SNMP functions.

typedef struct {
BYTE asnType;
union {
// RFC 1155 SimpleSyntax (subset of ISO ASN.1)
AsnInteger number;
AsnOctetString string;
AsnObjectIdentifier object;

// ISO ASN.1
AsnSequence sequence;

// RFC 1155 ApplicationSyntax
AsnIPAddress address;
AsnCounter counter;
AsnGauge gauge;
AsnTimeticks ticks;
AsnOpaque arbitrary;
} asnValue;
} AsnAny;

Members

asnType

Indicates the variable's type. This member can be only one of the following values:

Value Meaning Printed as
ASN_INTEGER Indicates an integer variable. %ld(long)
ASN_OCTETSTRING Indicates an octet string variable. putchar <oct>
ASN_OBJECTIDENTIFIER Indicates an object identifier variable. .1.2.3.4
ASN_SEQUENCE Indicates an ASN sequence variable. ASN_OCTET STRING
ASN_RFC1155_IPADDRESS Indicates an IP address variable. 157.578.160
ASN_RFC1155_COUNTER Indicates a counter variable. %lu (unsigned log)
ASN_RFC1155_GAUGE Indicates a gauge variable. %lu (unsigned log)
ASN_RFC1155_TIMETICKS Indicates a timeticks variable. %lu (unsigned log)
ASN_RFC1155_OPAQUE Indicates an opaque variable. 0x5 ox3 ox
ASN_RFC1213_DISPSTRING Indicates a display string variable. ASN_OCTET STRING

asnValue

Contains the variable's value. This member can be only one of the following:

Value Meaning
number Accesses an integer variable
string Accesses an octet string variable
object Accesses an object identifier variable
sequence Accesses an ASN sequence variable
address Accesses an IP address variable
counter Accesses a counter variable
gauge Accesses a gauge variable
ticks Accesses a timeticks variable
arbitrary Accesses an opaque variable
