Provides information for one file or directory to an enumeration.

Syntax

HRESULT PrjFillDirEntryBuffer(
  [in]           PCWSTR                      fileName,
  [in, optional] PRJ_FILE_BASIC_INFO         *fileBasicInfo,
  [in]           PRJ_DIR_ENTRY_BUFFER_HANDLE dirEntryBufferHandle
);

Parameters

[in] fileName

A pointer to a null-terminated string that contains the name of the entry

[in, optional] fileBasicInfo

Basic information about the entry to be filled.

[in] dirEntryBufferHandle

An opaque handle to a structure that receives information about the filled entries.

Return value

HRESULT_FROM_WIN32(ERROR_INSUFFICIENT_BUFFER) indicates that dirEntryBufferHandle doesn't have enough space for the new entry.

Remarks

The provider uses this routine to service a PRJ_GET_DIRECTORY_ENUMERATION_CB callback. When processing the callback, the provider calls this routine for each matching file or directory in the enumeration.

If this routine returns HRESULT_FROM_WIN32(ERROR_INSUFFICIENT_BUFFER) when adding an entry to the enumeration, the provider returns S_OK from the callback and waits for the next PRJ_GET_DIRECTORY_ENUMERATION_CB callback.

The provider resumes filling the enumeration with the entry it was trying to add when it got HRESULT_FROM_WIN32(ERROR_INSUFFICIENT_BUFFER).

If this routine returns HRESULT_FROM_WIN32(ERROR_INSUFFICIENT_BUFFER) for the first entry added during any invocation of a PRJ_GET_DIRECTORY_ENUMERATION_CB callback, the provider must return HRESULT_FROM_WIN32(ERROR_INSUFFICIENT_BUFFER) from the callback.
