SnmpMgrStrToOid function (mgmtapi.h)

[SNMP is available for use in the operating systems specified in the Requirements section. It may be altered or unavailable in subsequent versions. Instead, use Windows Remote Management, which is the Microsoft implementation of WS-Man.]

The SnmpMgrStrToOid function converts the string format of an object identifier to its internal object identifier structure. This function is an element of the SNMP Management API.


  [in]  LPSTR               string,
  [out] AsnObjectIdentifier *oid


[in] string

Pointer to a null-terminated string to convert.

[out] oid

Pointer to an object identifier variable to receive the converted value.

Return value

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero.


If the function succeeds, call the SnmpUtilOidFree function to free the memory allocated for the converted object identifier.

If an application passes a valid object identifier to SnmpMgrStrToOid, yet is unable to obtain the requested variable, then the syntax of the system group and object identifier is incorrect. This occurs because SnmpMgrStrToOid assumes that the object identifier is under the Internet MIB of the management subtree.

You must always precede the object identifier with a period (.) to obtain the correct system group (for example, "."). If an application passes the variable "", SnmpMgrStrToOid cannot interpret the object identifier correctly.
