set-stack-cushion

Arguments: spread

This function and stack-cushion allow inspection (stack-cushion) and modification (this function) of the current process's soft stack limit. The cushion value is either:

• number of nats between the current frame pointer and the soft stack limit (see The :nat and :unsigned-nat types in implementation.htm for a discussion of the nat type), or
• nil if there is no effective soft stack limit.

The value can be set when it is not nil. That is, when stack-cushion returns a true value, set-stack-cushion can be used to change the value (usually to provide a bigger cushion).
