Module `Lmdb.Env`Source

Collection of maps stored in a single memory-mapped file.

Sourcetype t

Sourcemodule Flags = Mdb.EnvFlags

Source

val create : 
  _ perm ->
  ?max_readers:int ->
  ?map_size:int ->
  ?max_maps:int ->
  ?flags:Flags.t ->
  ?mode:int ->
  string ->
  t

create perm path creates an environment with Ro or Rw permissions with data and lock files in the already existing directory path. If no separate directory is desired, Flags.no_subdir can be passed.

The returned handle is not garbage collected and should be closed explicitely to free locks and prevent corruption on async environments.

parameter map_size
Size of the memory map. Limited by the virtual address space.

parameter max_readers
Maximum number of threads/reader slots.

parameter max_maps
Maximum number of named maps.

parameter mode
The UNIX permissions to set on created files and semaphores. Default is 0o644.
