<div class="symptoms_section">

SYMPTOMS
You define a multibyte string for an MS-DOS device name. Then, you run a program that uses the QueryDosDeviceA function to retrieve a list of MS-DOS devices. In this scenario, you receive the following error message:

ERROR_MORE_DATA

This problem may occur even if you allocate a sufficient buffer size.

<div class="cause_section">

CAUSE
This problem occurs because the QueryDosDeviceA function does not consider multibyte strings during string conversion from UNICODE to ANSI.
