GetBinaryType function

Determines whether a file is an executable (.exe) file, and if so, which subsystem runs the executable file.

Syntax


BOOL WINAPI GetBinaryType(
  _In_   LPCTSTR lpApplicationName,
  _Out_  LPDWORD lpBinaryType
);

Parameters

lpApplicationName [in]

The full path of the file whose executable type is to be determined.

In the ANSI version of this function, the name is limited to MAX_PATH characters. To extend this limit to 32,767 wide characters, call the Unicode version of the function and prepend "\\?\" to the path. For more information, see Naming a File.

lpBinaryType [out]

A pointer to a variable to receive information about the executable type of the file specified by lpApplicationName. The following constants are defined.

ValueMeaning
SCS_32BIT_BINARY
0

A 32-bit Windows-based application

SCS_64BIT_BINARY
6

A 64-bit Windows-based application.

SCS_DOS_BINARY
1

An MS-DOS – based application

SCS_OS216_BINARY
5

A 16-bit OS/2-based application

SCS_PIF_BINARY
3

A PIF file that executes an MS-DOS – based application

SCS_POSIX_BINARY
4

A POSIX – based application

SCS_WOW_BINARY
2

A 16-bit Windows-based application

 

Return value

If the file is executable, the return value is nonzero. The function sets the variable pointed to by lpBinaryType to indicate the file's executable type.

If the file is not executable, or if the function fails, the return value is zero. To get extended error information, call GetLastError. If the file is a DLL, the last error code is ERROR_BAD_EXE_FORMAT.

Remarks

As an alternative, you can obtain the same information by calling the SHGetFileInfo function, passing the SHGFI_EXETYPE flag in the uFlags parameter.

Symbolic link behavior—If the path points to a symbolic link, the target file is used.
