28 //! \brief Initializes a CPUContextX86 structure from native context structures
29 //! on Mac OS X.
30 //!
31 //! \a flavor, \a state, and \a state_count may be supplied by exception
32 //! handlers in order for the \a context parameter to be initialized by the
33 //! thread state received by the exception handler to the extent possible. In
34 //! that case, whatever thread state specified by these three parameters will
35 //! supersede \a x86_thread_state32, \a x86_float_state32, or \a
36 //! x86_debug_state32. If thread state in this format is not available, \a
37 //! flavor may be set to `THREAD_STATE_NONE`, and all of \a x86_thread_state32,
38 //! \a x86_float_state32, and \a x86_debug_state32 will be honored.
39 //!
40 //! If \a flavor, \a state, and \a state_count are provided but do not contain
41 //! valid values, a message will be logged and their values will be ignored as
42 //! though \a flavor were specified as `THREAD_STATE_NONE`.
43 //!
44 //! \param[out] context The CPUContextX86 structure to initialize.
45 //! \param[in] flavor The native thread state flavor of \a state. This may be
46 //! `x86_THREAD_STATE32`, `x86_FLOAT_STATE32`, `x86_DEBUG_STATE32`,
47 //! `x86_THREAD_STATE`, `x86_FLOAT_STATE`, or `x86_DEBUG_STATE`. It may also
48 //! be `THREAD_STATE_NONE` if \a state is not supplied (and is `nullptr`).
49 //! \param[in] state The native thread state, which may be a casted pointer to
50 //! `x86_thread_state32_t`, `x86_float_state32_t`, `x86_debug_state32_t`,
51 //! `x86_thread_state`, `x86_float_state`, or `x86_debug_state`. This
52 //! parameter may be `nullptr` to not supply this data, in which case \a
53 //! flavor must be `THREAD_STATE_NONE`. If a “universal” structure is used,
54 //! it must carry 32-bit state data of the correct type.
55 //! \param[in] state_count The number of `natural_t`-sized (`int`-sized) units
56 //! in \a state. This may be 0 if \a state is `nullptr`.
57 //! \param[in] x86_thread_state32 The state of the thread’s integer registers.
58 //! \param[in] x86_float_state32 The state of the thread’s floating-point
59 //! registers.
60 //! \param[in] x86_debug_state32 The state of the thread’s debug registers.
