-FUNCTION
-        <<memcpy>>---copy memory regions, optimized for the mips processors
-
-ANSI_SYNOPSIS
-        #include <string.h>
-        void* memcpy(void *<[out]>, const void *<[in]>, size_t <[n]>);
-
-TRAD_SYNOPSIS
-        void *memcpy(<[out]>, <[in]>, <[n]>
-        void *<[out]>;
-        void *<[in]>;
-        size_t <[n]>;
-
-DESCRIPTION
-        This function copies <[n]> bytes from the memory region
-        pointed to by <[in]> to the memory region pointed to by
-        <[out]>.
-
-        If the regions overlap, the behavior is undefined.
-
-RETURNS
-        <<memcpy>> returns a pointer to the first byte of the <[out]>
-        region.
-
-PORTABILITY
-<<memcpy>> is ANSI C.
-
-<<memcpy>> requires no supporting OS subroutines.
-
-QUICKREF
-        memcpy ansi pure
