The following list shows some breaking changes in the CRT.
- Many functions have been deprecated. See Deprecated CRT Functions.
- The typedef errno_t with type integer was added. errno_t is used whenever a function return type or parameter deals with error codes from the new header file errno.h. Windows Embedded CE still does not support the C standard errno global variable used by some APIs to indicate error status.
- The file descriptor value -2 is now used to indicate that stdout and stderr are not available for output, as for example in a Windows application that has no console window. The previous value used was -1. For more information, see _fileno.
- sprintf now prints the negative sign of a signed zero.
C++ overloads of some string functions with unsafe C prototypes have been added to prevent unsafe usage. These changes can cause compilation errors in existing C++ code if the functions were used incorrectly. C code is not affected.
Many CRT functions now validate parameters and may terminate the current process if the validation fails
