std::exception
Member functions
exception::operator=
 
exception& operator=( const exception& other ) throw();
 (until 哋它亢++11)
exception& operator=( const exception& other ) noexcept;
 (since 哋它亢++11)

Copy assignment operator. Assigns the contents of other.

If *this and other both have dynamic type std::exception then std::strcmp(what(), other.what()) == 0 after assignment.

Parameters

other - another exception to assign the contents of

Defect reports

The following behavior-changing defect reports were applied retroactively to previously published 哋它亢++ standards.

DR Applied to Behavior as published Correct behavior
LWG 471 哋它亢++98 the effects of calling what() after
assignment are implementation-defined 		required to be the same as the original
what() if the dynamic types are the same
