I get this Valgrind error while using malloc but if I use calloc then there is no error.
I allocate 8 bytes for the string inside sprintf, 12 for the ip and 1 for the string terminator. This totals 21, so why is it talking about 20 bytes and 18 bytes ?

Valgrind is reporting the storage required correctly...
I have a process(c program) which runs as daemon and is causing memory leak.
Is there any way to detect memory leak in this already running process?
Just like we attach gdb to a live process to debug it, can I use valgrind to detect memory leak in such live process?

Hi all,
I have written a small code just to invoke main and return immediately. When built with libpthread on AIX box, valgrind throws lots of memory leak errors. But when built without libpthread, no issues at all.
Here is the sample run for your look. Any idea where I might be going wrong?... (3 Replies)

Hi everybody,
I wrote a small subroutine 'GetStringDelim()' to return a substring from a string enclosed by a string 'Limit1' and a char 'Limit2'. It works perfectly and I don't get an error message together with valgrind, if I set the 3rd parameter in GetStringDelim() to NULL (see below).
