NAME

       memstomp - detect function calls with overlapping memory regions

SYNOPSIS

       memstomp [-dk] application [argument...]

       memstomp -h

DESCRIPTION

       The  memstomp  utility  identifies  function calls that use overlapping memory regions in situations when such an overlap is not allowed by
       various standards. When a problem is detected, memstomp displays a backtrace to help you debug  the  problem,  and  if  executed  with  the
       --debug-info  command  line option, it even uses the available debugging information. Since the backtrace code is not thread safe, memstomp
       also allows you to use the --kill option to immediately terminate the analyzed program when an invalid function call is detected.

       This version of memstomp inspects the following function calls: memcpy(), memccpy(), mempcpy(), strcpy(), stpcpy(),  strncpy(),	stpncpy(),
       strcat(), strncat(), wmemcpy(), wmempcpy(), wcscpy(), wcsncpy(), wcscat(), and wcsncat().

OPTIONS

       -d, --debug-info
	      Make use of debugging information to produce more detailed stack traces.

       -k, --kill
	      Kill the analyzed application when a problem is detected.

       -h, --help
	      Display usage information and exit.

       -q, --quiet
	      Be less verbose

DESCRIPTION

     The functions implement string manipulation operations over wide character strings.  For a detailed description, refer to documents for the
     respective single-byte counterpart, such as memchr(3).

STANDARDS

     These functions conform to ISO/IEC 9899:1999 (``ISO C99''), with the exception of wcpcpy(), wcpncpy(), wcscasecmp(), wcsdup(), wcsncasecmp(),
     and wcsnlen(), which conform to IEEE Std 1003.1-2008 (``POSIX.1''); and wcslcat() and wcslcpy(), which are extensions.
