1//! Stable C ABI for rpic.

3//! String-returning functions return a NUL-terminated, heap-allocated C string
4//! (free with [`rpic_free_string`]) or NULL on error. Byte-returning functions
5//! write the length to `out_len` and return a heap buffer (free with
6//! [`rpic_free_bytes`]) or NULL on error. All input strings mu …
