USE_MSVCRT
Use the USE_MSVCRT macro to instruct the Build utility to use the multithreaded runtime libraries in a DLL for your build.
Syntax
USE_MSVCRT = 1
Comments
You must set one of the following macros equal to one in your Sources file. The other ones should not be defined at all (you may not define them equal to zero or equal to "").
The different libraries specified by these macros shown in the following table:
| Macro | Effect |
|---|---|
USE_MSVCRT |
Use the multithreaded run-time libraries in a DLL. In the free build environment, this library is Msvcrt.lib. In the checked build environment, this library is Msvcrtd.lib. |
| USE_LIBCMT | Use the multithreaded static libraries. |
| USE_LIBCNTPR | Use the kernel run-time libraries. |
| USE_NTDLL | Use Ntdll.dll (the DLL for NT-based operating systems). |
| USE_NOLIBS | Do not use any run-time libraries. |
If none of these macros are defined, the default behavior is to statically link to the single-threaded run-time libraries. However, starting with the Windows Driver Kit (WDK) for Windows Vista, support for these libraries was removed and you will now get a link failure because the libraries were not found. To avoid this failure, set one of these macros (preferably USE_MSVCRT) to 1.
Note You should never list Msvcrt.lib or Msvcrtd.lib in TARGETLIBS. However, you can list Ntdll.lib in TARGETLIBS.
