PerfRegInfoType enumeration (perflib.h)

  • Article

Indicates the types of information that you can request about a performance counter set by calling the PerfQueryCounterSetRegistrationInfo function.

Syntax

typedef enum _PerfRegInfoType {
  PERF_REG_COUNTERSET_STRUCT = 1,
  PERF_REG_COUNTER_STRUCT,
  PERF_REG_COUNTERSET_NAME_STRING,
  PERF_REG_COUNTERSET_HELP_STRING,
  PERF_REG_COUNTER_NAME_STRINGS,
  PERF_REG_COUNTER_HELP_STRINGS,
  PERF_REG_PROVIDER_NAME,
  PERF_REG_PROVIDER_GUID,
  PERF_REG_COUNTERSET_ENGLISH_NAME,
  PERF_REG_COUNTER_ENGLISH_NAMES
} PerfRegInfoType;

Constants

 
PERF_REG_COUNTERSET_STRUCT
Value: 1
Gets the registration information for a counter set and all of the counters it contains as a PERF_COUNTERSET_REG_INFO block. The block includes a PERF_COUNTERSET_REG_INFO structure followed by one or

more PERF_COUNTER_REG_INFO structures.
PERF_REG_COUNTER_STRUCT
Gets the registration information for a performance counter as a PERF_COUNTER_REG_INFO structure.

Use the requestLangId parameter of the PerfQueryCounterSetRegistrationInfo function to specify the counter identifier.
PERF_REG_COUNTERSET_NAME_STRING
Gets a null-terminated UTF16-LE string that indicates the name of the counter set.

Use the requestLangId parameter of the PerfQueryCounterSetRegistrationInfo function to specify the preferred locale of the result.
PERF_REG_COUNTERSET_HELP_STRING
Gets a null-terminated UTF16-LE string that contains the help string for the counter set.

Use the requestLangId parameter of the PerfQueryCounterSetRegistrationInfo function to specify the preferred locale of the result.
PERF_REG_COUNTER_NAME_STRINGS
Gets the names of the performance counters in the counter set as a PERF_STRING_BUFFER_HEADER block.

The block includes a PERF_STRING_BUFFER_HEADER structure, followed by one

or more PERF_STRING_COUNTER_HEADER structures, followed by string data that indicates the counter names.

Use the requestLangId parameter of the PerfQueryCounterSetRegistrationInfo function to specify the preferred locale of the result.
PERF_REG_COUNTER_HELP_STRINGS
Gets the help strings for the performance counters in the counter set as a PERF_STRING_BUFFER_HEADER block.

The block includes a PERF_STRING_BUFFER_HEADER structure, followed by one

or more PERF_STRING_COUNTER_HEADER structures, followed by string data that contains the help strings.

Use the requestLangId parameter of the PerfQueryCounterSetRegistrationInfo function to specify the preferred locale of the result.
PERF_REG_PROVIDER_NAME
Gets a null-terminated UTF-16LE string that indicates the name of the provider for the counter set.
PERF_REG_PROVIDER_GUID
Gets the GUID of the provider for the counter set.
PERF_REG_COUNTERSET_ENGLISH_NAME
Gets a null-terminated UTF-16LE string that contains the name of the counter set in English. This value is equivalent to setting the requestCode parameter to PERF_REG_COUNTERSET_NAME_STRING and the requestLangId parameter to 0 when you call the PerfQueryCounterSetRegistrationInfo function.
PERF_REG_COUNTER_ENGLISH_NAMES
Gets the English names of the performance counters in the counter set as a PERF_STRING_BUFFER_HEADER block.

The block includes a PERF_STRING_BUFFER_HEADER structure, followed by one

or more PERF_STRING_COUNTER_HEADER structures, followed by string data that indicates the counter names. This value is equivalent to setting the requestCode parameter to PERF_REG_COUNTER_NAME_STRINGS and the requestLangId parameter to 0 when you call the PerfQueryCounterSetRegistrationInfo function.
