list_timerenv_init Subroutine

public subroutine list_timerenv_init(list, initial_capacity)

Allocates the internal data-structures of the given list. This has to be called before any of the other routines. For deallocation call list_[valuetype]_destroy.

Arguments

Type IntentOptional Attributes Name
type(list_timerenv_type), intent(inout) :: list
integer, intent(in), optional :: initial_capacity

The initial size of the internal array (default=11).
