Boost.Context provides the class fixedsize_stack
which models the stack-allocator concept. In contrast
to protected_fixedsize_stack it does not append a guard
page at the end of each stack. The memory is simply managed by std::malloc() and std::free().
#include <boost/context/fixedsize_stack.hpp> template< typename traitsT > struct basic_fixedsize_stack { typedef traitT traits_type; basic_fixesize_stack(std::size_t size = traits_type::default_size()); stack_context allocate(); void deallocate( stack_context &); } typedef basic_fixedsize_stack< stack_traits > fixedsize_stack;
stack_context allocate()
traits_type::minimum:size()
<= size
and ! traits_type::is_unbounded() &&
( traits_type::maximum:size() >= size).
Allocates memory of at least size
Bytes and stores a pointer to the stack and its actual size in sctx. Depending on the architecture
(the stack grows downwards/upwards) the stored address is the highest/lowest
address of the stack.
void deallocate( stack_context
& sctx)
sctx.sp is valid, traits_type::minimum:size() <= sctx.size and !
traits_type::is_unbounded()
&& (
traits_type::maximum:size()
>= sctx.size).
Deallocates the stack space.
