uwx_step(3X) uwx_step(3X) NAME
uwx_step() - step one frame SYNOPSIS
DESCRIPTION
is part of the Unwind Express Library for Integrity systems; see uwx(3X). steps back one frame from the current context and updates the context to reflect the state of the new frame. The return pointer becomes the new IP (instruction pointer), the previous stack pointer becomes the new stack pointer, the backing store pointer is adjusted to point to the previous frame's registers, the previous frame state becomes the new current frame marker, and all preserved registers are updated with the values they had in that frame. (If has been used to disable floating-point register tracking, the preserved floating-point registers will not be updated.) Parameters env A pointer to an unwind environment object. RETURN VALUE
returns on success. If the current frame is at the bottom of the call stack, it returns and the current context is unchanged. If the cur- rent frame is a signal frame (or some other ABI-dependent context frame), it returns and the current context is unchanged. All other sta- tus codes indicate errors; see uwx(3X) for error codes. AUTHOR
