Notes

When S3L_USE_MMAP or S3L_USE_SHMGET is used on a 32-bit platform, the part of an S3L array owned by a single SMP cannot exceed 2 gigabytes.

When S3L_USE_MALLOC or S3L_USE_MEMALIGN64 is used, the part of the array owned by any single process can not exceed 2 gigabytes.

If these size restrictions are violated, an S3L_ERR_MEMALLOC will be returned. On 64-bit platforms, the upper bound is equal to the system's maximum available memory.
