/******************************************************************
* modified JCD 27 Apr-88 for AMIGA
* cext.h -- extensions to c to make it more portable
* Copyright 1989 Carnegie Mellon University
*
*******************************************************************
cext must provide the following definitions:
true -- a constant
false -- a boolean constant
private -- defined as static, used to declare local functions
public -- defined as empty string, used to declare exported functions
boolean -- a new type
byte -- unsigned 8-bit quantity
ushort -- unsigned 16-bit quantity
ulong -- unsigned 32-bit quantity
Pointer -- pointer to char, a generic pointer
ABS() -- absolute value of any type of number
MAX() -- maximum of two numbers
MIN() -- minimum of two numbers
ROUND() -- round a double to long
NULL -- pointer to nothing, a constant
EOS -- end of string, a constant '\0'
MALLOC(x) -- allocates x bytes
FREE(x) -- frees something from MALLOC
AVAILMEM -- tells how much memory is available.
(N.B.: no parens, no args.)
EXIT(n) -- calls exit(n) after shutting down/deallocating resources
*****************************************************************************/
