Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. unix.ByteSliceToString converts null-terminated byte slice to string
  2. unix.NsecToTimespec converts nanoseconds to Timespec structure
  3. unix.TimespecToNsec converts Timespec structure back to nanoseconds
  4. unix.Getpagesize returns positive system memory page size
