NAME
uwx_get_abi_context_code() - return ABI and context code from current context
SYNOPSIS
#include <uwx.h>
int uwx_get_abi_context_code(struct uwx_env *
env );
DESCRIPTION
uwx_get_abi_context_code()
is part of the Unwind Express Library for Integrity systems; see
uwx(3X).
uwx_get_abi_context_code()
returns the abi and context parameters recorded in the
unwind descriptors for the frame. This routine returns the two values in a single int as ((abi << 8) | con-
text ). This entry point should be called only after
uwx_step() returns the status code
UWX_ABI_FRAME
, indicating that a signal frame has been reached.
On HP-UX, the architected value for the abi code is 1, and a context code of 1 identifies a signal context
frame. Other values of the context code are reserved for future or internal use.
Parameters
env A pointer to an unwind environment object.
RETURN VALUE
uwx_get_abi_context_code()
returns the abi and context codes for the current frame. If the
current frame is not a signal context frame, the return value is undefined.
