thread_create - create a thread
#include <zircon/syscalls.h> zx_status_t zx_thread_create(zx_handle_t process, const char* name, size_t name_size, uint32_t options, zx_handle_t* out);
thread_create() creates a thread within the specified process.
Upon success a handle for the new thread is returned. The thread will not start executing until thread_start() is called.
name is silently truncated to a maximum of ZX_MAX_NAME_LEN-1 characters.
Thread handles may be waited on and will assert the signal ZX_THREAD_TERMINATED when the thread stops executing (due to thread_exit() being called).
process is the controlling process object for the new thread, which will become a child of that process.
For thread lifecycle details see thread object.
process must be of type ZX_OBJ_TYPE_PROCESS and have ZX_RIGHT_MANAGE_THREAD.
On success, thread_create() returns ZX_OK and a handle (via out) to the new thread. In the event of failure, a negative error value is returned.
ZX_ERR_BAD_HANDLE process is not a valid handle.
ZX_ERR_WRONG_TYPE process is not a process handle.
ZX_ERR_ACCESS_DENIED process does not have the ZX_RIGHT_MANAGE_THREAD right.
ZX_ERR_INVALID_ARGS name or out was an invalid pointer, or options was non-zero.
ZX_ERR_NO_MEMORY Failure due to lack of memory. There is no good way for userspace to handle this (unlikely) error. In a future build this error will no longer occur.
