GetDeviceDriverFileName function

Retrieves the path available for the specified device driver.

Syntax

DWORD WINAPI GetDeviceDriverFileName(
  _In_   LPVOID ImageBase,
  _Out_  LPTSTR lpFilename,
  _In_   DWORD nSize
);

Parameters

ImageBase [in]

The load address of the device driver.

lpFilename [out]

A pointer to the buffer that receives the path to the device driver.

nSize [in]

The size of the lpFilename buffer, in characters. If the buffer is not large enough to store the path plus the terminating null character, the string is truncated.

Return value

If the function succeeds, the return value specifies the length of the string copied to the buffer, not including any terminating null character.

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

Remarks

Starting with Windows 7 and Windows Server 2008 R2, Psapi.h establishes version numbers for the PSAPI functions. The PSAPI version number affects the name used to call the function and the library that a program must load.

If PSAPI_VERSION is 2 or greater, this function is defined as K32GetDeviceDriverFileName in Psapi.h and exported in Kernel32.lib and Kernel32.dll. If PSAPI_VERSION is 1, this function is defined as GetDeviceDriverFileName in Psapi.h and exported in Psapi.lib and Psapi.dll as a wrapper that calls K32GetDeviceDriverFileName.

Programs that must run on earlier versions of Windows as well as Windows 7 and later versions should always call this function as GetDeviceDriverFileName. To ensure correct resolution of symbols, add Psapi.lib to the TARGETLIBS macro and compile the program with –DPSAPI_VERSION=1. To use run-time dynamic linking, load Psapi.dll.
