FARENA - Simple Fortran Arena Allocator for Intrinsic Arrays

supported type(kind)

    i32 => integer(kind=c_int32_t)
    i64 => integer(kind=c_int64_t)
    sp => real(kind=c_float)
    dp => real(kind=c_double)

Returned pointers must all be marked contiguous.

public API:

    type(arena_type)
        => init([size_i32, size_i64, size_sp, size_dp])   ! default size will hold 1 GB, optional 32-bit integers for maximum size
        => init64([size_i32, size_i64, size_sp, size_dp]) ! default size will hold 1 GB, optional 64-bit integers for maximum size
        => reset()                                        ! reset internal counter to reuse the same arena
        => free()                                         ! explicitly deallocate arena's memory
        => gptr(dim1, dim2, ..., dimN, ptr)               ! return N-D pointer to arrays of intrinsic types
                                                          !   supports i32, i64, sp, dp
                                                          !   supports rank 1-15 arrays
                                                          !   rank 1 arrays specified by 32/64-bit integer dimension
                                                          !   rank 2-15 specified by 32-bit integer dimensions
