/**
 * The NtCreateProfileEx routine creates a profile object for performance monitoring with group affinity.
 *
 * \param ProfileHandle A pointer to a variable that receives the handle to the profile object.
 * \param Process Optional handle to the process to be profiled. If NULL, the current process is used.
 * \param ProfileBase The base address of the region to be profiled.
 * \param ProfileSize The size, in bytes, of the region to be profiled.
 * \param BucketSize The size, in bytes, of each bucket in the profile buffer.
 * \param Buffer A pointer to a buffer that receives the profile data.
 * \param BufferSize The size, in bytes, of the buffer.
 * \param ProfileSource The source of the profiling data (KPROFILE_SOURCE).
 * \param GroupCount The number of group affinities provided.
 * \param GroupAffinity A pointer to an array of GROUP_AFFINITY structures specifying processor groups to profile.
 * \return NTSTATUS Successful or errant status.
