- These memory tracking routines are provided to zlib and track all of zlib's
- allocations and deallocations, check for LIFO operations, keep a current
- and high water mark of total bytes requested, optionally set a limit on the
- total memory that can be allocated, and when done check for memory leaks.
-
- They are used as follows:
-
- z_stream strm;
- mem_setup(&strm) initializes the memory tracking and sets the
- zalloc, zfree, and opaque members of strm to use
- memory tracking for all zlib operations on strm
- mem_limit(&strm, limit) sets a limit on the total bytes requested -- a
- request that exceeds this limit will result in an
- allocation failure (returns NULL) -- setting the
- limit to zero means no limit, which is the default
- after mem_setup()
- mem_used(&strm, "msg") prints to stderr "msg" and the total bytes used
- mem_high(&strm, "msg") prints to stderr "msg" and the high water mark
- mem_done(&strm, "msg") ends memory tracking, releases all allocations
- for the tracking as well as leaked zlib blocks, if
- any. If there was anything unusual, such as leaked
- blocks, non-FIFO frees, or frees of addresses not
- allocated, then "msg" and information about the
- problem is printed to stderr. If everything is
- normal, nothing is printed. mem_done resets the
- strm members to Z_NULL to use the default memory
- allocation routines on the next zlib initialization
- using strm.
