A CIL-only DLL sets flag 0x2000 to 1, while a CIL-only .exe has flag 0x2000 set to zero:
| Flag | Value | Description |
|---|---|---|
IMAGE_FILE_RELOCS_STRIPPED |
0x0001 | Shall be zero |
IMAGE_FILE_EXECUTABLE_IMAGE |
0x0002 | Shall be one |
IMAGE_FILE_32BIT_MACHINE |
0x0100 | Shall be one if and only if COMIMAGE_FLAGS_32BITREQUIRED is one (§25.3.3.1) |
IMAGE_FILE_DLL |
0x2000 | The image file is a dynamic-link library (DLL). |
For the flags not mentioned above, flags 0x0010, 0x0020, 0x0400 and 0x0800 are implementationspecific, and all others should be zero (§II.24.1).
