Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

     To use the C++ _set_new_handler functions, you must write an
     exception-handling function and then pass it as an argument to
     _set_new_handler. To facilitate the easy declaration of this new
     handler, three pointer-to-function types (_PNH, _PNHH, and
     _PNHB) are defined in NEW.H.
 
     Type      Description
 
     _PNH      Pointer to a function that returns type int and takes an
               argument of type size_t. Use size_t to specify the amount
               of space to be allocated.
               See: __near, __far
 
     _PNHH     Pointer to a function that returns type int and takes two
               arguments──the type unsigned long and the type size_t
               arguments specified to the huge new operator.
               See: __huge
 
     _PNHB     Pointer to a function that returns type int and takes two
               arguments──the type __segment and the type size_t
               arguments specified to the based new operator. Your
               function must ensure the correct binding of the segment
               variable to its return value.
