thread_write_state() writes one aspect of state of the thread. The thread state may only be written when the thread is halted for an exception or the thread is suspended.
The thread state is highly processor specific. See the structures in zircon/syscalls/debug.h for the contents of the structures on each platform.
See thread_read_state for the list of available states and their corresponding values.
thread_write_state() returns ZX_OK on success. In the event of failure, a negative error value is returned.
ZX_ERR_BAD_HANDLE handle is not a valid handle.
ZX_ERR_WRONG_TYPE handle is not that of a thread.
ZX_ERR_ACCESS_DENIED handle lacks ZX_RIGHT_WRITE.
ZX_ERR_INVALID_ARGS kind is not valid, buffer is an invalid pointer, or len doesn't match the size of the structure expected for kind.
ZX_ERR_NO_MEMORY Temporary out of memory failure.
ZX_ERR_BAD_STATE The thread is not stopped at a point where state is available. The thread state may only be read when the thread is stopped due to an exception.
ZX_ERR_NOT_SUPPORTED kind is not supported. This can happen, for example, when trying to read a register set that is not supported by the hardware the program is currently running on.
