stack_setbounds - update stack boundaries
int stack_setbounds(const stack_t *sp);
The stack_setbounds() function updates the current base and
bounds of the stack for the current thread to the bounds
specified by the stack_t structure pointed to by sp. The
ss_sp member refers to the virtual address of the base of
the stack memory. The ss_size member refers to the size of
the stack in bytes. The ss_flags member must be set to 0.
Upon successful completion, stack_setbounds() returns 0.
Otherwise, -1 is returned and errno is set to indicate the
The stack_setbounds() function will fail if:
The sp argument does not refer to a valid address or
the ss_sp member of the stack_t structure pointed to
by sp points to an illegal address.
The ss_sp member of the stack_t structure pointed to
by sp is not properly aligned, the ss_size member is
too small or is not properly aligned, or the ss_flags
member is non-zero.
The stack_setbounds() function is intended for use by appli-
cations that are managing their own alternate stacks.
