The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.
std::mask_array<T>::~mask_array – std::mask_array<T>::~mask_array Synopsis ~mask_array(); Destroys the indexes in the array. The elements referred to by the object are not modified.
std::mask_array – std::mask_array Synopsis Defined in header <valarray> template< class T > class mask_array; std::mask_array is a helper template used by the valarray_subscript_operator with std::valarray<bool> argument. It has reference semantics and provides access to the subset of the valarray consisting of the elements whose indices correspond to true values in the std::valarray<bool> mask. Member types…
std::map<Key,T,Compare,Allocator>::~map – std::map<Key,T,Compare,Allocator>::~map Synopsis ~map(); Destructs the container.

Complexity Linear in the size of the container.
std::malloc – std::malloc Synopsis Defined in header<cstdlib> void *malloc(std::size_t size); Allocates size bytes of uninitialized storage.
