Article
02/22/2024

TraceLogging wrapper macro that adds custom information about the event into the PDB.

Syntax

void TraceLoggingCustomAttribute(
  [in]  key,
  [in]  value
);

Parameters

[in] key

A string literal with the key for the custom attribute.

[in] value

A string literal with the value of the custom attribute.

Return value

None

Remarks

TraceLoggingCustomAttribute("key", "value") can be used as a parameter to an invocation of a TraceLoggingWrite macro. Most TraceLogging events do not need custom attributes and should not use TraceLoggingCustomAttribute.

Custom attributes are stored in the PDB. They are not available at runtime.
