/* Smartalloc.h       Copyright Clinton Staley 1991
 * 
 * Smartalloc provides an malloc version which checks for several possible
 * errors:
 *
 * 1. Failure of malloc call for any reason
 * 2. Attempt to free memory not allocated by malloc, or already freed.
 * 3. Writing past the end of malloc-ed memory
 * 4. Failure to free memory by some point in the program.
 *
 * Use smartalloc by including smartalloc.h in any file that calls malloc
 * or free.  Also, compile smartalloc.c along with your other .c files.
 * If you make any of errors 1-3 above, smartalloc will report the error
 * and the file/line on which it occured.  To find out if you have left
 * memory unfreed, call report_space().  If any unfreed memory is
 * outstanding, report_space will report the number of bytes of unfreed
 * memory.  If no memory is unfreed, report_space remains silent.
 *
 * All rights to this package are reserved by its author.  Duplication of
 * source or object code is permitted only with the author's permission.
