| 4 | <strong>Function</strong> - Start a processor. | |
| 5 | <h3>SYNOPSIS</h3> | |
| 6 | <pre> | |
| 7 | <strong>#include<mach/mach_host.h></strong> | |
| 8 | ||
| 9 | <strong>kern_return_t processor_start</strong> | |
| 10 | <strong>(processor_t</strong> <var>processor</var><strong>);</strong> | |
| 11 | </pre> | |
| 12 | <h3>PARAMETERS</h3> | |
| 13 | <dl> | |
| 14 | <dt> <var>processor</var> | |
| 15 | <dd> | |
| 16 | [in processor send right] | |
| 17 | The processor to be controlled. | |
| 18 | </dl> | |
| 19 | <h3>DESCRIPTION</h3> | |
| 20 | <p> | |
| 21 | The <strong>processor_start</strong> function allows privileged software | |
| 22 | to start a processor in | |
| 23 | a multi-processor that so allows it. A newly started processor | |
| 24 | is assigned to the | |
| 25 | default processor set. The interpretation of this operation | |
| 26 | is machine dependent. | |
| 27 | <h3>NOTES</h3> | |
| 28 | <p> | |
| 29 | This operation is machine dependent. It may do nothing. | |
| 30 | <h3>CAUTIONS</h3> | |
| 31 | <p> | |
| 32 | The ability to restart an exited processor is machine dependent. | |
| 33 | <h3>RETURN VALUES</h3> | |
| 34 | <dl> | |
| 35 | <dt> <strong>KERN_FAILURE</strong> | |
| 36 | <dd> | |
| 37 | The operation was not performed. A likely reason is that it | |
| 38 | is not supported on this processor. | |
