std::runtime::wasi::process

Source: std/runtime/wasi/process.slk

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

Role#

std::runtime::wasi::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/wasi/process.slk.
• The canonical module name is std::runtime::wasi::process.
• WASI Preview 1 does not expose an OS executable-path query in this module; argv-backed views are available through std::args.
• WASI Preview 1 also has no POSIX effective-user identity; its effective_user_id implementation returns the documented zero placeholder.
• WASI Preview 1 has no process-group primitive. Its setpgid compatibility stub fails, so the high-level hosted child API reports process-group setup as unsupported instead of claiming isolation.
• 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.
