Helper functions

Boost.Context provides easy access to the stack related limits defined by the environment.

std::size_t default_stacksize();

std::size_t minimum_stacksize();

std::size_t maximum_stacksize();

bool is_stack_unbound();

std::size_t pagesize();

std::size_t page_count( std::size_t stacksize);

`std::size_t default_stacksize()`

Returns:: Returns a default stack size, which may be platform specific. The present implementation returns a value of 256 kB.

`std::size_t minimum_stacksize()`

Returns:: Returns the minimum size in bytes of stack defined by the environment.
Throws:: Nothing.

`std::size_t maximum_stacksize()`

Preconditions:: is_stack_unbound() returns false.
Returns:: Returns the maximum size in bytes of stack defined by the environment.
Throws:: Nothing.

`bool is_stack_unbound()`

Returns:: Returns true if the environment defines no limit for the size of a stack.
Throws:: Nothing.

`std::size_t pagesize()`

Returns:: Returns how many bytes the operating system allocates for one page.
Throws:: Nothing.

`std::size_t page_count( std::size_t stacksize)`

Returns:: Returns how many pages have to be allocated for a stack of stacksize bytes.
Throws:: Nothing.
