NAME
     AG_CPUInfo	-- agar	architecture information structure

SYNOPSIS
     #include <agar/core.h>

DESCRIPTION
     The agar AG_CPUInfo interface provides some information about the current
     architecture and architecture extensions.

INTERFACE
     void AG_GetCPUInfo(AG_CPUInfo *info)

     The AG_GetCPUInfo() function returns CPU information into an existing
     info structure.

STRUCTURE DATA
     For the AG_CPUInfo	structure:

     const char	*arch	 A string describing the architecture (e.g., "alpha",
			 "i386", etc).

     char vendorID[13]	 A vendor ID string (architecture-specific).

     Uint32 ext		 A list	of architecture	extensions that	have some rel-
			 evance	to user	applications (see ARCHITECTURE
			 EXTENSIONS below).
