void *memset(
   void *dest,
   int c,
   size_t count
);
wchar_t *wmemset(
   wchar_t *dest,
   wchar_t c,
   size_t count
);

例子：-------------------------------------------------------------------------------------------------------------

int main( void )
{
     char buffer[] = "This is a test of the memset function";

     printf( "Before: %s\n", buffer );
     memset( buffer, '*', 4 );
     printf( "After: %s\n", buffer );
}
