Control whether garbage collection is enabled using a boolean argument (true for enabled, false for disabled). Returns previous GC state. Disabling garbage collection should be used only with extreme caution, as it can cause memory use to grow without bound.


  1. Enable garbage collection:

    julia> gc_enable(true)

    This example enables garbage collection.

  2. Disable garbage collection:

    julia> gc_enable(false)

    This example disables garbage collection.

  3. Check previous GC state:
    julia> previous_state = gc_enable(true)

    It returns the previous garbage collection state.

Common mistake example:

julia> gc_enable(1)
ERROR: MethodError: no method matching gc_enable(::Int64)

In this example, the argument provided is not a boolean (true or false). Make sure to provide a valid boolean argument to enable or disable garbage collection.
