 * Flushes the instruction cache for the specified process.
 *
 * @param ProcessHandle A handle to the process whose instruction cache is to be flushed.
 * @param BaseAddress A pointer to the base address of the memory region to be flushed. This parameter can be NULL.
 * @param RegionSize The size of the memory region to be flushed, in bytes.
 * @return NTSTATUS Successful or errant status.
 * @remarks Applications should call NtFlushInstructionCache if they generate or modify code in memory. The CPU cannot detect the change, and may execute the old code it cached.
