AsnAny

The AsnAny structure contains an SNMP variable type and value. This structure is a member of the RFC1157VarBind2_6KC47 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
