GetDeviceDriverBaseNameA function (psapi.h)
Retrieves the base name of the specified device driver.
DWORD GetDeviceDriverBaseNameA( [in] LPVOID ImageBase, LPSTR lpFilename, [in] DWORD nSize );
The load address of the device driver. This value can be retrieved using the EnumDeviceDrivers function.
The size of the lpBaseName buffer, in characters. If the buffer is not large enough to store the base name plus the terminating null character, the string is truncated.
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.
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 K32GetDeviceDriverBaseName in Psapi.h and exported in Kernel32.lib and Kernel32.dll. If PSAPI_VERSION is 1, this function is defined as GetDeviceDriverBaseName in Psapi.h and exported in Psapi.lib and Psapi.dll as a wrapper that calls K32GetDeviceDriverBaseName.
Programs that must run on earlier versions of Windows as well as Windows 7 and later versions should always call this function as GetDeviceDriverBaseName. 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.
For an example, see Enumerating all Device Drivers in the System.
The psapi.h header defines GetDeviceDriverBaseName as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors.
