Typedefs

typedef void(* new_handler )()

Functions

new_handler set_new_handler (new_handler) throw ()
 Takes a replacement handler as the argument, returns the previous handler.


Detailed Description

The header new defines several functions to manage dynamic memory and handling memory allocation errors; see http://gcc.gnu.org/onlinedocs/libstdc++/18_support/howto.html#4 for more.

Definition in file new.


Typedef Documentation

typedef void(* std::new_handler)()
 

If you write your own error handler to be called by new, it must be of this type. Definition at line 66 of file new.

These are replaceable signatures:
