number of processes the snapshot contains. A pointer to the first |

entry, of type <structname>sg_process_stats</structname> is |

returned, and <parameter>entries</parameter> can be used to iterate |

These functions compare two sg_process_stats entries, and return an |
| 123 |
+ |
int to represent which one is greater. The main use of these functions |
| 124 |
+ |
is to be passed to qsort to sort the sg_process_stats by the given type. |
