Package org.lwjgl.system.jemalloc


@NullMarked package org.lwjgl.system.jemalloc
Contains bindings to the jemalloc library. jemalloc is a general purpose malloc implementation that emphasizes fragmentation avoidance and scalable concurrency support.

The jemalloc shared library that comes with LWJGL is configured with:

  • --with-jemalloc-prefix=je_
  • --enable-lazy-lock=no (FreeBSD)
  • --disable-stats
  • --disable-fill
  • --disable-cxx
  • --disable-initial-exec-tls (FreeBSD, Linux & macOS)
  • --disable-zone-allocator (macOS)

The shared library may be replaced with a custom build that has more features enabled.

Dynamic configuration (for enabled features) is also possible, using either the MALLOC_CONF environment variable or the MALLCTL NAMESPACE and the mallctl* functions.
