std::experi...do_allocate(3) C++ Standard Libary std::experi...do_allocate(3) NAME std::experimental::pmr::monotonic_buffer_resource::do_allocate - std::ex- perimental::pmr::monotonic_buffer_resource::do_allocate Synopsis virtual void* do_allocate( std::size_t bytes, std::size_t (library fun- damentals TS) alignment ); Allocates storage. If the current buffer has sufficient unused space to fit a block with the specified size and alignment, allocates the return block from the current buffer. Otherwise, this function allocates a new buffer by calling upstream_resource()->allocate(n, m), where n is not less than the greater of bytes and the next buffer size and m is not less than alignment. It sets the new buffer as the current buffer, increases the next buffer size by an implementation- defined growth factor (which is not necessarily integral), and then allocates the return block from the newly allocated buffer. Return value A pointer to allocated storage of at least bytes bytes in size, aligned to the specified alignment if such alignment is supported, and to alig- nof(std::max_align_t) otherwise. Exceptions Throws nothing unless calling allocate() on the upstream memory resource throws.
