freemen()                Free a Previously Allocated DOS Memory Block
 
 #include   <dos.h>
 
 int        freemem(seg);
 unsigned   seg;                         Segment address
 
    freemem() frees a memory block allocated by a previous call to
    allocmem().  'seg' is the segment address of that block.
 
    Returns:    freemem() returns 0 on success.  On error, -1 is returned
                and 'errno' (defined in <stdlib.h>) is set to ENOMEM
                (insufficient memory).
