### CArclib::ArcSNMPWithOid

The ArcSNMPWithOid method returns the information about SNMP OID.

virtual ARC_STATUS ArcSNMPWithOid( int *oid, int *length, unsigned char *szCommunity, int *ret_oid, unsigned char *tag, unsigned char **var, int *var_len );

#### Parameters:

[IN]

oid: An integer array contains OID name

length: The length of OID.

szCommunity: Community string

[OUT]

ret_oid: An integer array contains OID name returned from RAID subsystem.

tag: The SNMP tag of the returning value.

var: The answer of the returned OID.

var_len: The length of the answer.

#### Return Values

This method returns the ARC_STATUS.

#### Note:

The parameter of length acts both input and output, in the input mode this filed is the length of oid,

and in the output mode this filed is the length of the ret_oid.

The szCommunity must terminates with a null-character

#### Example:

unsigned char tag; int name[] = {1,3,6,1,4,1,18928,1,1,1,1}; int ret_oid[20]; int length = sizeof(name) / sizeof(int); unsigned char *var = NULL; int ret_var_len = 0; char string[256]; char *result_str = NULL; int result_len = 0; int long_ret = 0; // ignore the initialization process of the CArclib stat = ar[0].ArcSNMPWithOid( (int *)name, (int *)&length, (unsigned char *)"public", ret_oid, &tag, &var, (int *)&ret_var_len ); if ( stat == ARC_SUCCESS ) { if ( tag == 0x02 /*ASN_INTEGER*/ ) { long_ret = *((long *)var); } else if ( tag == 0x04 /*ASN_OCTET_STR*/ ) { result_str = (char *)var; result_len = ret_var_len; result_str[result_len] = 0; sprintf(string,"%s", result_str); } }
