Getting started

The Peios SDK is the C-ABI library family you use to talk to Peios from your own programs — access control, the registry, and events. Its first and largest member is libpeios.

The packages that make up libpeios, the headers you include, and how to compile and link against the library — with pkg-config, by hand, statically, and from non-C languages.

The rules every libpeios function follows — how success and failure are reported, how the two-call buffer protocol works, how builders and views manage memory, and how file descriptors and constants are handled. Learn these once and they hold across the whole SDK.

A small, complete C program that parses a security descriptor, reads its owner, and formats the SID back to text — putting the two-call protocol, views, and the error model to work.

The Peios SDK ships first-class Rust bindings — the peios-sys raw FFI crate and the safe, idiomatic peios wrapper. This page is the on-ramp; the crate's rustdoc is the API reference.
