of setlocale. In contrast, LabWindows/CVI links standalone executables to the shared
library libc.so, which contains the fully functional versi on of setlocale.
Between LabWindows/CVI and Sun Solaris
The following incompatibilities exist between LabWindows/CVI and Sun Solaris:
• LabWindows/CVI does not support the long long data type some header files on
Solaris 2 use. In LabWindows/CVI, you cannot use that data type or call functions that
use that data type.
• LabWindows/CVI implements the data type long double as an 8-byte object, in the
same way that it implements double. Sun Solaris implements long double as a
16-byte object. As a result, Sun Solaris functions that use long double do not work
properly in LabWindows/CVI.
• The LabWindows/CVI implementation of the printf and scanf family of functions
does not support the Sun Solaris implementation of long double.
• LabWindows/CVI does not support wide character constants (wchar_t) of the form
L'ab'.
• The data types jmp_buf and sigjmp_buf that the header file setjmp.h defines are
different for LabWindows/CVI and Sun Solaris. The LabW indows/C VI versions of thes e
buffers are larger than the Sun Solaris versions because LabWindows/CVI stores
additional debugging information in them. As a result, you must be careful when you use
jmp_buf and sigjmp_buf objects among multiple files. In particular, if you compile a
file in LabWindows/CVI with debugging enabled and the file uses setjmp or longjmp,
then your program must include the LabWindows/CVI version of setjmp.h to handle
those functions correctly. The same is true for sigjmp_buf, sigsetjmp, and
siglongjmp.
