# # This is a little helper to use dmalloc within gdb, use it via # "source dmalloc.gdb" # # It will provide a command dmalloc, which will ask the user for # arguments to provide to the dmalloc application. The output will be # in gdb format and will be parsed by gdb. # # Its main purpose is to generate breaks at allocations of unfreed # memory (via dmalloc -a ...). # # As gdb's language is very basic, there is no back substitution and # variable arguments to user defined commands. Therefore the user # defined command dmalloc will use a shell escape to ask the user for # the arguments to the dmalloc applications. The dmalloc applications # will execute with the provided arguments and write the output to a # temporary file. This temporary file will then be read by gdb and # deleted afterwards. # # November 10, 1998 - Jens Krinke # define dmalloc echo Enter dmalloc options: shell read arg; dmalloc -g $arg > /tmp/dmalloc-gdb source /tmp/dmalloc-gdb shell rm -f /tmp/dmalloc-gdb show env DMALLOC_OPTIONS # the following will not work if no symboltable is loaded, but that # doesn't matter. break dmalloc_error end
