Unmodified Fortran/C POSIX pipe interfaces in the restricted Linux sandbox. Following the upstream process_open_read example, the consumer opens a local printf command, reads and checks the integers 7 and 11, verifies end of output and requires a successful process_close status. Commands run under the ordinary sandbox restrictions; this does not add network or host-system access. Interactive terminals, graphical subprocesses, arbitrary process behavior, write pipes and Windows portability are not verified.

Reviewed procedures
These mappings have pinned source evidence. A checked package example may exercise only some of them; source review is not a numerical benchmark.
