%%% `%' and `#' are comments !!!!!!!

|
|
% This file must be called `.ccmalloc' and is searched for in the
|
|
% current directory and in the home directory of the user. If it
|
|
% does not exist then the default values mentioned below are used.
|
|
|
|
% It is also the currently only available user manual ;-) So here
|
|
% is a reading hint. First have a look at the short one line
|
|
% descriptions of each option ...
|
|
|
|
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
|
|
% with `file' the executable is specified [a.out]
|
|
% ----------------------------------------------------------------------
|
|
% This should not be necessary for Linux and Solaris because the proc
|
|
% file system can be used to find argv[0].
|
|
%
|
|
% (the rest of this comment only applies to other OS)
|
|
%
|
|
% For other OS you should use this option unless the executable is
|
|
% in the current directory or its name is `a.out'.
|
|
%
|
|
% If you do not specify this then ccmalloc tries to find an executable
|
|
% in the current directory that matches the running program starting
|
|
% with `a.out'. For this process it must call `nm' on each executable
|
|
% file in the directory which may be time consuming. With this option
|
|
% you can speed up this process.
|
|
%
|
|
% You can also specify absolute or relative path names. This is
|
|
% necessary if you do not start your program from the current directory.
|
|
% But you can also simply link or name your program to `a.out'.
|
|
|
|
%file FILE
|
|
|
|
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
|
|
% `log' specify the logfile [stderr]
|
|
% ----------------------------------------------------------------------
|
|
% The default is to use stderr. The argument to `log' is the name of
|
|
% the file you want to write to. It can also be `stdout' or `-' which
|
|
% sets stdout as logfile. If the logfile is stdout or stderr and is
|
|
% connected to a terminal then the output is slightly different.
|
|
%
|
|
% For big programs the logfile can be really big. To reduce the size
|
|
% you can use a small chain length (see `chain-length' below). The other
|
|
% possibility is to use compressed logfiles. This can be done by
|
|
% specifying a logfile name with a `.gz' (or a `.Z') suffix. This means
|
|
% that gnuzip (resp. compress) is used to compress the output.
|
|
|
|
log report
|
|
|
|
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
|
|
% `logpid' specify the logfile
|
|
% ----------------------------------------------------------------------
|
|
% Can be used alternatively to the `log' command if you want to use
|
|
% ccmalloc for debugging parallel applications where several copies of
|
|
% the program you are debugging must be run simoultaneously. In this
|
|
% case you can not use `log' because you do not want to write to the same
|
|
% log file. Using `logpid' uses a file name ending with the <pid> of
|
|
% the process which means the name is unique even if several copies of
|
|
% your program are run simoultaneously.
|
|
%
|
|
% If you use the compressing suffixes then the <pid> is inserted before
|
|
% the suffix (e.g. `logpid ccmalloc.log.gz' uses `ccmalloc.log.<pid>.gz'
|
|
% as the name for the log file).

% `dont-log-chain' skip info about certain chains []
|
|
% ----------------------------------------------------------------------
|
|
% This command may be repeated any number of times. The argument to this
|
|
% command is a comma-separated list of function-or-file-and-line
|
|
% specifications. Garbage allocated from a callchain that contains this
|
|
% subchain anywhere will _not_ be logged.
|
|
%
|
|
% The comma-separated list should not contain any spaces. E.g. not:
|
|
% main, foo, bar
|
|
% but:
|
|
% main,foo,bar
|
|
% A function-or-file-and-line specification is a string followed by an
|
|
% optional colon and number, for example: main or main:14 or main.c or
|
|
% main.c:15. Note that the string is compared with both the function and
|
|
% the file name, if available. If main.c happens to be a function name,
|
|
% that will cause a match (for that string at least).
|
|
% Not specifying a line number will match any line number. If line number
|
|
% information is not available, anything will match!
|
|
% Not specifying a name (e.g. ,,,) will match an unknown function name.
|
|
% Not giving any parameters at all, will match a chain containing at least
|
|
% one unknown function.
