- `ptmalloc2', a malloc implementation for multiple threads without
- lock contention, by Wolfram Gloger <wg@malloc.de>.
-
- VERSION 2.7.0
-
- This work is mainly derived from malloc-2.7.0 by Doug Lea
- <dl@cs.oswego.edu>, which is available from:
-
- ftp://gee.cs.oswego.edu/pub/misc/malloc.c
-
- This trimmed-down header file only provides function prototypes and
- the exported data structures. For more detailed function
- descriptions and compile-time options, see the source file
- `malloc.c'.
