Memory stats are accessed through get_memory_stats() call. This |
| 2 |
returns a pointer to a static mem_stat_t |

typedef struct{ |

long long total; |

total contains the total memory in bytes. |
| 12 |
free is the total free memory in bytes. |
| 13 |
used is the total used memory in bytes. |
| 14 |
cache is the cache used in bytes. |
| 15 |
|
| 16 |
cache is not available in all operating systems. Solaris being a key |
| 17 |
one that it isn't. free memory and cache memory can sometimes be |
| 18 |
linked. |

Swap stats are accessed through get_swap_stats() call. This returns a |
| 21 |
pointer to a static swap_stat_t |
| 22 |
|
| 23 |
typedef struct{ |
| 24 |
long long total; |
| 25 |
long long used; |
| 26 |
long long free; |
| 27 |
}swap_stat_t; |

Freebsd requires kmem privilages to be able to do this call. Making the |
| 31 |
program setgid kmem should be sufficent. |
| 32 |
|
| 33 |
TODO |
| 34 |
Add a function to hold open the FD to kmem privilages could be dropped. |
