std::runtime::process

Source: std/runtime/process.slk

This is the exact canonical documentation page for std::runtime::process.

Role#

std::runtime::process is an implementation-facing runtime module in the shipped std/** tree. It exists so higher-level stdlib surfaces can delegate platform or runtime-specific behavior without changing their public module names.

Canonical Context#

Use the following owning docs for the substantive API/design context for this module:

• runtime
• process

Notes#

• The shipped source for this module is std/runtime/process.slk.
• The canonical module name is std::runtime::process.
• It includes the implementation-facing executable_path_owned bridge used by std::process::executable_path.
• It includes the effective_user_id bridge used by std::process::effective_user_id; hosted POSIX delegates to geteuid(2) and widens its u32 ABI result to u64, while WASI Preview 1 returns its documented zero placeholder.
• It provides implementation-facing set_process_group_self and kill_process_group operations for the checked ownership surface in std::process::child. The setter can only place the calling child into a group led by itself; the signal helper requires a positive, private group identity and negates it internally for POSIX kill(2).
• This page is intentionally implementation-oriented. Downstream users should usually start with the higher-level std module docs listed above unless they are working on the runtime layer itself.
