DeleteUmsCompletionList function (winbase.h)

Deletes the specified user-mode scheduling (UMS) completion list. The list must be empty.

Warning

As of Windows 11, user-mode scheduling is not supported. All calls fail with the error ERROR_NOT_SUPPORTED.

Syntax

BOOL DeleteUmsCompletionList(
  [in] PUMS_COMPLETION_LIST UmsCompletionList
);

[in] UmsCompletionList

A pointer to the UMS completion list to be deleted. The CreateUmsCompletionList function provides this pointer.

If the function succeeds, it returns a nonzero value.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

If the completion list is shared, the caller is responsible for ensuring that no active UMS thread holds a reference to the list before deleting it.
