Module rustix::param

Process parameters.

These values correspond to sysconf in POSIX, and the auxv array in Linux. Despite the POSIX name “sysconf”, these aren’t system configuration parameters; they’re process configuration parameters, as they may differ between different processes on the same system.

linux_hwcap
