PRB: OpenFile API returns ERROR_BUFFER_OVERFLOW Error (137233)


The information in this article applies to:

  • Microsoft Win32 Software Development Kit (SDK) 4.0
This article was previously published under Q137233

SYMPTOMS

If the OpenFile API is passed a path that is longer than MAXPATHNAME, OpenFile returns ERROR_BUFFER_OVERFLOW.

One of the parameters to OpenFile is a pointer to the pathname to open. Another parameter is a pointer to an OFSTRUCT structure that will receive information. OFSTRUCT contains a fixed size buffer, szPathName that holds MAXPATHNAME bytes. A path longer than that is not valid.

RESOLUTION

Consider using CreateFile instead of OpenFile.

STATUS

This behavior is by design.
