+//! \brief Saves the CPU context.
+//!
+//! The CPU context will be captured as accurately and completely as possible,
+//! containing an atomic snapshot at the point of this function’s return. This
+//! function does not modify any registers.
+//!
+//! \param[out] cpu_context The structure to store the context in.
+//!
+//! \note On x86_64, the value for `%%rdi` will be populated with the address of
+//! this function’s argument, as mandated by the ABI. If the value of
+//! `%%rdi` prior to calling this function is needed, it must be obtained
+//! separately prior to calling this function. For example:
+//! \code
+//! uint64_t rdi;
+//! asm("movq %%rdi, %0" : "=m"(rdi));
+//! \endcode
+void CaptureContext(NativeCPUContext* cpu_context);
