There are 4 functions which you need to implement on your system:



	int   liballoc_lock();

	int   liballoc_unlock();

	void* liballoc_alloc(int);

	int   liballoc_free(void*,int);



1) Have a look at liballoc.h for information about what each function is 

supposed to do.





2) Have a look at linux.c for an example of how to implement the library 

on linux. 





NOTE: There are two ways to build the library.



    1) Compile the library with a new system file. For example, I've

	   left linux.c with the default distribution. It gets compiled

	   directly into the liballoc_linux.so file.



	2) Implement the functions in your application and then just

	   link against the default liballoc.so library when you compile

	   your app.





QUICK START

-------------



You can simply type: "make linux" to build the linux shared

library.  Thereafter, you can link it directly into your applications

during build or afterwards by export the LD_PRELOAD environment

variable. 





To run bash with the library, for example:



    LD_PRELOAD=/full/path/to/liballoc.so bash





The above command will pre-link the library into the application,

essentially replacing the default malloc/free calls at runtime. It's

quite cool.
