# Sample RC file for the debug malloc library
# Rename this to .dmallocrc and place in your $HOME directory to
# activate.  See dmalloc.info for more information.

# This file maps tags to certain combinations of debug tokens.  The 
# tags here are provided as an example.  You can also roll your own.  
# Lines in this file should have the form:
#
#	tag	token1, token2, ...
#
# To use the above line you say 'dmalloc tag' which enables the
# debugging facilities token1, token2, ...  You must pass the output
# from dmalloc through your shell's eval command to change your
# environment.  See malloc.info for more information.
#
# Lines can end with a \ meaning it continues onto the next line.
# Lines beginning with '#' and empty lines are ignored

# log-bad-space			log actual bytes from bad pointers
# log-nonfree-space		log actual bytes in non-freed pointers
# log-elapsed-time		log elapsed-time for allocated pointer
# log-current-time		log current-time for allocated pointers
#
# check-fence			check fence-post areas
# check-heap			do general heap checking
# check-lists			verify internal heap linked-lists
# check-blank			check to see if blank space is overwritten
# check-funcs			check the arguments of some routines
#
# catch-signals			shutdown the library on SIGHUP, SIGINT, SIGTERM
# realloc-copy			always copy data to a new pointer when realloc
# free-blank			overwrite space that is freed
# error-abort			abort the program (and dump core) on errors
# alloc-blank			blank space that is to be alloced
# heap-check-map		log a heap-map every time the heap is checked
# print-messages		print errors and messages to STDERR
# catch-null			abort program if library can't get sbrk space
# never-reuse			never reuse memory that has been freed
# allow-nonlinear		allow non-linear heap space
# allow-free-null		allow the freeing of NULL pointers
# error-dump			dump core on error and then continue
