Structure used to query the GC statistics (profiling information). More fields could be added in the future. To preserve compatibility new fields should be added only to the end, and no deprecated fields should be removed from.

Fields

heapsize_full: GC_word

Heap size in bytes (including the area unmapped to OS). Same as value of GC_get_heap_size() + GC_get_unmapped_bytes().

free_bytes_full: GC_word

Total bytes contained in free and unmapped blocks. Same as result of GC_get_free_bytes() + GC_get_unmapped_bytes().

unmapped_bytes: GC_word

Amount of memory unmapped to OS. Same as the value returned by GC_get_unmapped_bytes().

bytes_allocd_since_gc: GC_word

Number of bytes allocated since the recent collection. Same as the value returned by GC_get_bytes_since_gc().

allocd_bytes_before_gc: GC_word

Number of bytes allocated before the recent garbage collection. The value may wrap. Same as the result of GC_get_total_bytes() - GC_get_bytes_since_gc().

non_gc_bytes: GC_word

Number of bytes not considered candidates for garbage collection. Same as the value returned by GC_get_non_gc_bytes().

gc_no: GC_word

Garbage collection cycle number. The value may wrap. Same as the value returned by GC_get_gc_no().

markers_m1: GC_word

Number of marker threads (excluding the initiating one). Same as the value returned by GC_get_parallel() (or 0 if the collector is single-threaded).

bytes_reclaimed_since_gc: GC_word

Approximate number of reclaimed bytes after the recent garbage collection.

reclaimed_bytes_before_gc: GC_word

Approximate number of bytes reclaimed before the recent garbage collection. The value may wrap.

expl_freed_bytes_since_gc: GC_word

Number of bytes freed explicitly since the recent garbage collection. Same as the value returned by GC_get_expl_freed_bytes_since_gc().

obtained_from_os_bytes: GC_word

Total amount of memory obtained from OS, in bytes.
