Malloc bindings

Allows you to set/query the behaviour of malloc. The functions in this module may not be implemented on your platform.

type mallinfo = {
arena : int;
non-mmapped space allocated from system
ordblks : int;
number of free chunks
smblks : int;
number of fastbin blocks
hblks : int;
number of mmapped regions
hblkhd : int;
space in mmapped regions
usmblks : int;
maximum total allocated space
fsmblks : int;
space available in freed fastbin blocks
uordblks : int;
total allocated space
fordblks : int;
total free space
keepcost : int;
top-most, releasable (via malloc_trim) space
}
type opt = 
|TRIM_THRESHOLD
Maximum amount of unused top-most memory to keep before releasing via malloc_trim in free().
|TOP_PAD
Amount of extra `padding' space to allocate or retain whenever sbrk is called.
|MMAP_THRESHOLD
Request size threshold for using mmap() to service a request. Requests of at least this size that cannot be allocated using already-existing space will be serviced via mmap.
|MMAP_MAX
Maximum number of requests to simultaneously service using mmap.
|CHECK_ACTION
Malloc options
val mallinfo : (unit -> mallinfo) Core.Std.Or_error.t
mallinfo () Returns information on the state of malloced memory (C-heap).
val mallopt : (opt -> int -> unit) Core.Std.Or_error.t
mallopt opt n sets malloc configuration option opt to n.
val malloc_trim : (int -> unit) Core.Std.Or_error.t
malloc_trim n release all but n bytes of freed top-most memory back to the system. Raises Failure if unsuccessful.
val malloc_stats : (unit -> unit) Core.Std.Or_error.t
malloc_stats () prints brief summary statistics on stderr.
