#include <ucontext.h> 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 error.
The stack_setbounds() function will fail if: EFAULT
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 applications that are managing their own alternate stacks.
