Create a new process.
#include <zircon/syscalls.h> zx_status_t zx_process_create(zx_handle_t job, const char* name, size_t name_size, uint32_t options, zx_handle_t* proc_handle, zx_handle_t* vmar_handle);
zx_process_create() creates a new process.
Upon success, handles for the new process and the root of its address space are returned. The thread will not start executing until
zx_process_start() is called.
name is silently truncated to a maximum of
When the last handle to a process is closed, the process is destroyed.
Process handles may be waited on and will assert the signal ZX_PROCESS_TERMINATED when the process exits.
job is the controlling job object for the new process, which will become a child of that job.
options can contain zero or the following flag:
job must be of type ZX_OBJ_TYPE_JOB and have ZX_RIGHT_MANAGE_PROCESS.
Caller job policy must allow ZX_POL_NEW_PROCESS.
zx_process_create() returns ZX_OK, a handle to the new process (via proc_handle), and a handle to the root of its address space (via vmar_handle). In the event of failure, a negative error value is returned.
ZX_ERR_BAD_HANDLE job is not a valid handle.
ZX_ERR_WRONG_TYPE job is not a job handle.
ZX_ERR_ACCESS_DENIED job does not have the ZX_RIGHT_WRITE right (only when not ZX_HANDLE_INVALID).
ZX_ERR_INVALID_ARGS name, proc_handle, or vmar_handle was an invalid pointer, or options contained invalid options.
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.
ZX_ERR_BAD_STATE The job object is in the dead state.
