SYNOPSIS
       lmdbg-grep [OPTIONS] _awk_expr_ [files...]

DESCRIPTION
       lmdbg-grep takes	output of lmdbg-stat or	lmdbg-run as input and outputs

       variables can be	used in	awk_exp	expression :

	      bytes  the number	of allocated bytes,

	      allocs the number	of calls of malloc/calloc/memalign/posix_mema-
		     lign,

	      max    the maximum number	of  bytes  allocated  per  malloc/cal-
		     loc/memalign/posix_memalign function,

	      peak   the peak number of	allocated bytes,

	      leaks  the number	of allocated but not freed bytes,

	      address
		     address returned by memory	allocation function,

	      source source code filename,

	      funcname
		     function name,

	      addrline
		     address in	the stacktrace.
       The  following  variables are numeric: bytes, allocs, max, peak,	leaks;
       others contain string values.

OPTIONS
       -h     Display the help message.

       -V     Display the lmdbg	version.
