CAtlTransactionManager::CreateFile

Creates or opens a file, file stream, or directory as a transacted operation.

inline HANDLE CAtlTransactionManager::CreateFile(
   LPCTSTR lpFileName,
   DWORD dwDesiredAccess,
   DWORD dwShareMode,
   LPSECURITY_ATTRIBUTES lpSecurityAttributes,
   DWORD dwCreationDisposition,
   DWORD dwFlagsAndAttributes,
   HANDLE hTemplateFile
);

Parameters

  • lpFileName
    The name of an object to be created or opened.

  • dwDesiredAccess
    The access to the object, which can be summarized as read, write, both, or neither (zero). The most commonly used values are GENERIC_READ, GENERIC_WRITE, or both: GENERIC_READ | GENERIC_WRITE.

  • dwShareMode
    The sharing mode of an object, which can be read, write, both, delete, all of these, or none: 0, FILE_SHARE_DELETE, FILE_SHARE_READ, FILE_SHARE_WRITE.

  • lpSecurityAttributes
    A pointer to a SECURITY_ATTRIBUTES structure that contains an optional security descriptor and also determines whether or not the returned handle can be inherited by child processes. The parameter can be NULL.

  • dwCreationDisposition
    An action to take on files that exist and do not exist. This parameter must be one of the following values, which cannot be combined: CREATE_ALWAYS, CREATE_NEW, OPEN_ALWAYS, OPEN_EXISTING, or TRUNCATE_EXISTING.

  • dwFlagsAndAttributes
    The file attributes and flags. This parameter can include any combination of the available file attributes (FILE_ATTRIBUTE_*). All other file attributes override FILE_ATTRIBUTE_NORMAL. This parameter can also contain combinations of flags (FILE_FLAG_*) for control of buffering behavior, access modes, and other special-purpose flags. These combine with any FILE_ATTRIBUTE_* values.

  • hTemplateFile
    A valid handle to a template file with the GENERIC_READ access right. The template file supplies file attributes and extended attributes for the file that is being created. This parameter can be NULL.

Return Value

Returns a handle that can be used to access the object.

Remarks

This wrapper calls the CreateFileTransacted function.
