Source: [`std/runtime/posix/process.slk`](https://github.com/oro-computer/silk/blob/master/std/runtime/posix/process.slk)

This is the exact canonical documentation page for [`std::runtime::posix::process`](/silk/docs/std/runtime-posix-process/).

## Role

[`std::runtime::posix::process`](/silk/docs/std/runtime-posix-process/) is an implementation-facing runtime module in the shipped [`std/**`](https://github.com/oro-computer/silk/tree/master/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](/silk/docs/std/runtime/)
- [process](/silk/docs/std/process/)

## Notes

- The shipped source for this module is [`std/runtime/posix/process.slk`](https://github.com/oro-computer/silk/blob/master/std/runtime/posix/process.slk).
- The canonical module name is [`std::runtime::posix::process`](/silk/docs/std/runtime-posix-process/).
- It binds the hosted `silk_rt_process_executable_path_owned` helper for
 platform executable-path queries.
- It binds the POSIX `geteuid(2)` operation with the hosted `uid_t` ABI width
 (`u32`) used by [`std::process::effective_user_id`](/silk/docs/std/process/). The higher runtime layer
 widens that value to the public `u64` identity type.
- It binds `setpgid(2)` for the higher runtime layer's child-only process-group
 setup. Raw group selection remains an implementation detail and is not part
 of the high-level child API.
- 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.
