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.

#
