thread_start - start execution on a thread
#include <magenta/syscalls.h> mx_status_t mx_thread_start(mx_handle_t thread, uintptr_t entry, uintptr_t stack, uintptr_t arg1, uintptr_t arg2);
thread_start() causes a thread to begin execution at the program counter specified by entry and with the stack pointer set to stack. The arguments arg1 and arg2 are arranged to be in the architecture specific registers used for the first two arguments of a function call before the thread is started. All other registers are zero upon start.
When the last handle to a thread is closed, the thread is destroyed.
Thread handles may be waited on and will assert the signal MX_THREAD_TERMINATED when the thread stops executing (due to thread_exit*() being called.
thread_start() returns MX_OK on success. In the event of failure, a negative error value is returned.
MX_ERR_BAD_HANDLE thread is not a valid handle.
MX_ERR_WRONG_TYPE thread is not a thread handle.
MX_ERR_ACCESS_DENIED The handle thread lacks MX_RIGHT_WRITE.
MX_ERR_BAD_STATE thread is not ready to run or the process thread is part of is no longer alive.
