The GNU C library +and most other Unix implementations require the @code{ss_sp} value of +the @code{uc_stack} element to point to the base of the memory region +allocated for the stack and the size of the memory region is stored in +@code{ss_size}. There are implements out there which require +@code{ss_sp} to be set to the value the stack pointer will have (which +can depending on the direction the stack grows be different).
