//! \param[out] context The structure to initialize.
//! \param[in] seed The seed value. Initializing two context structures of the
//!     same type with identical seed values should produce identical context
//!     structures. Initialization with a different seed value should produce
//!     a different context structure. If \a seed is `0`, \a context is zeroed
//!     out entirely except for the CPUContext::architecture field, which will
//!     identify the context type. If \a seed is nonzero, \a context will be
//!     populated entirely with nonzero values.
