PDH_COUNTER_PATH_ELEMENTS_W structure (pdh.h)

The PDH_COUNTER_PATH_ELEMENTS structure contains the components of a counter path.

Syntax

typedef struct _PDH_COUNTER_PATH_ELEMENTS_W {
  LPWSTR szMachineName;
  LPWSTR szObjectName;
  LPWSTR szInstanceName;
  LPWSTR szParentInstance;
  DWORD  dwInstanceIndex;
  LPWSTR szCounterName;
} PDH_COUNTER_PATH_ELEMENTS_W, *PPDH_COUNTER_PATH_ELEMENTS_W;

Members

szMachineName

Pointer to a null-terminated string that specifies the computer name.

szObjectName

Pointer to a null-terminated string that specifies the object name.

szInstanceName

Pointer to a null-terminated string that specifies the instance name. Can contain a wildcard character.

szParentInstance

Pointer to a null-terminated string that specifies the parent instance name. Can contain a wildcard character.

dwInstanceIndex

Index used to uniquely identify duplicate instance names.

szCounterName

Pointer to a null-terminated string that specifies the counter name.

Remarks

This structure is used by PdhMakeCounterPath to create a counter path and by PdhParseCounterPath to parse a counter path.

When you allocate memory for this structure, allocate enough memory for the member strings, such as szCounterName, that are appended to the end of this structure.
