_memavl()                Return Size of Memory Available

 #include   <malloc.h>                   Required for declarations only

 unsigned int   _memavl(void);

    _memavl() returns the approximate number of bytes that can be
    allocated in the default data segment by malloc(), calloc(),
    realloc() (using the small and medium memory models), and _nmalloc()
    (in all memory models).

    Returns:    Approximate number of bytes available in the default data
                segment.

      Notes:    Compact, large, and huge memory model programs may have
                additional space outside the default segment.

                _fmalloc() may be able to allocate additional space
                outside the default data segment.

  -------------------------------- Example ---------------------------------

    The following statement reports the approximate number of bytes
    available in the default data segment.

            #include <malloc.h>
            #include <stdio.h>      /* for printf */

            main()
            {
                printf("approximately %u bytes available\n",
                       _memavl());
            }
