If you opened this file directly from disk, your browser may be directly suppressing JavaScript functionality: certain browsers perform this suppression on local files (but not files delivered by web servers) for security reasons.

If you access the manual through the hub's Web GUI, the functionality will not be suppressed because the hub is a web server.
Alternatively, your browser may allow you to explicitly disable the security setting that suppresses functionality. See the CodeSonar FAQ for more information.

LANG.FUNCS.MDELETE : Missing delete

要旨

[C++14 and later] The code overloads some, but not all, forms of the delete, placement delete, delete[], or placement delete[] operator.

Form	Example
unsized	void operator delete ( void* ptr ) noexcept;
sized	void operator delete ( void* ptr, std::size_t sz ) noexcept;

Form	Example
unsized, unaligned	void operator delete ( void* ptr ) noexcept;
unsized, aligned	void operator delete ( void* ptr, std::align_val_t al ) noexcept;
sized, unaligned	void operator delete ( void* ptr, std::size_t sz ) noexcept;
sized, aligned	void operator delete ( void* ptr, std::size_t sz, std::align_val_t al ) noexcept;
