AsnAny

The AsnAny structure contains an SNMP variable type and value. This structure is a member of the SnmpVarBind structure that is used as a parameter in many of the SNMP functions. This structure is not used by the WinSNMP API functions.

Members

asnType

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

Value	Meaning
ASN_INTEGER	Indicates a 32-bit signed integer variable.
ASN_INTEGER32	Indicates a 32-bit signed integer variable.
ASN_UNSIGNED32	Indicates a 32-bit unsigned integer variable.
ASN_COUNTER64	Indicates a counter variable that increases until it reaches a maximum value of (2^64) – 1.
ASN_OCTETSTRING	Indicates an octet string variable.
ASN_BITS	Indicates a variable that is an enumeration of named bits.
ASN_OBJECTIDENTIFIER	Indicates an object identifier variable.
ASN_SEQUENCE	Indicates an ASN sequence variable.
ASN_IPADDRESS	Indicates an IP address variable.
ASN_COUNTER32	Indicates a counter variable.
ASN_GAUGE32	Indicates a gauge variable.
ASN_TIMETICKS	Indicates a timeticks variable.
ASN_OPAQUE	Indicates an opaque variable.

asnValue

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

Value	Meaning
number	Accesses a 32-bit signed integer variable.
unsigned32	Accesses a 32-bit unsigned integer variable.
counter64	Accesses a counter variable that increases until it reaches a maximum value of (2^64) – 1.
String	Accesses an octet string variable.
bits	Accesses a variable that is an enumeration of named bits with non-negative, contiguous values, starting at zero.
Object	Accesses an object identifier variable.
sequence	Accesses an ASN sequence variable.
address	Accesses an IP address variable.
counter	Accesses a counter variable that increases until it reaches a maximum value of (2^32) – 1.
