NAME
freemem - deallocate a block of heap memory
SYNOPSIS
int freemem(addr, len)
char *addr;
int len;
DESCRIPTION
_F_r_e_e_m_e_m deallocates a contiguous block of memory previously
obtained with GETMEM(2), and returns it to the free list.
Argument _a_d_d_r specifies the lowest address of the block
being deallocated, and argument _l_e_n specifies the length of
the block in bytes. In this version, memory is allocated in
multiples of four bytes to guarantee that sufficient space
is available in each block to link it onto the free list.
However, the length passed to both _g_e_t_m_e_m and _f_r_e_e_m_e_m is
rounded automatically, so the user need not be aware of any
extra space in the allocated block.
