Previously, the mac version was under client/ and win under util/win/. This cl brings them all together under util/misc/ and combines common test code.

|
//! This function searches for an `EXC_CRASH` handler in the same manner that
|
|
//! the kernel does, and sends it an exception message to that handler in the
|
|
//! format that the handler expects, considering the behavior and thread state
|
|
//! flavor that are registered for it. The exception sent to the handler will be
|
|
//! ::kMachExceptionSimulated, not `EXC_CRASH`.
|
|
//!
|
|
//! Typically, the CRASHPAD_SIMULATE_CRASH() macro will be used in preference to
|
|
//! this function, because it combines the context-capture operation with the
|
|
//! raising of a simulated exception.
|
|
//!
|
|
//! This function returns normally after the exception message is processed. If
|
|
//! no valid handler was found, or no handler processed the exception
|
|
//! successfully, a warning will be logged, but these conditions are not
|
|
//! considered fatal.
|
|
//!
|
|
//! \param[in] cpu_context The thread state to pass to the exception handler as
|
|
//! the exception context, provided that it is compatible with the thread
|
|
//! state flavor that the exception handler accepts. If it is not
|
|
//! compatible, the correct thread state for the handler will be obtained by
|
|
//! calling `thread_get_state()`.
