Compaq AAR04BCTE manual Ooid, ESNMP API Routines ooid, Oid

eSNMP API Routines o_oid

o_oid

Loads an OID value into the VARBIND structure with the appropriate type. This function does not allocate the VARBIND structure.

Format

int o_oid ( VARBIND *vb, OBJECT *obj, OID *oid );

Arguments

vb

A pointer to the VARBIND structure that is supposed to receive the data.

If the original value in the VARBIND structure is not null, this routine attempts to free it. So if you dynamically allocate memory or issue the malloc command to allocate your own VARBIND structure, fill the structure with zeros before using it.

obj

A pointer to the OBJECT structure for the MIB variable associated with the OID in the VARBIND structure.

oid

The value to be inserted into the VARBIND structure as data. For more information about OID length and values, see Chapter 3.

The real type as defined in the object structure must be ESNMP_TYPE_OBJECT_

IDENTIFIER.

Return Values

ESNMP_MTHD_noError	The routine completed successfully.
ESNMP_MTHD_genErr	An error occurred.
Example

#include <esnmp.h>

#include "ip_tbl.h" <-- for ipNetToMediaEntry_type definition

VARBIND	*vb	=	method->varbind;
OBJECT	*object	=	method->object;

ipNetToMediaEntry_type *data;
