16 Library introduction [library]

The C++ standard library provides a default version of the following handler function ([support]):

• (1.1)
  terminate_handler

A C++ program may install different handler functions during execution, by supplying a pointer to a function defined in the program or the library as an argument to (respectively):

• (2.1)
  set_new_handler
• (2.2)
  set_terminate

See also subclauses [alloc.errors], Storage allocation errors, and [support.exception], Exception handling.

A C++ program can get a pointer to the current handler function by calling the following functions:

• (3.1)
  get_new_handler
• (3.2)
  get_terminate

Calling the set_* and get_* functions shall not incur a data race.

A call to any of the set_* functions shall synchronize with subsequent calls to the same set_* function and to the corresponding get_* function.
