ARG_MAX is configurable for your system. This is the total bytes in all of the arguments passed to exec. If you try this:
Code:
grep 'ARG_MAX' /usr/include/limits.h

it will display the value for your system. It is usually pretty big.

In my case i could not find any "ARG_MAX" in /usr/include/limits.h file.. Then i think there should be a default value .. what it is?

Look into /usr/include/linux/limits.h

Code:
#define ARG_MAX       131072    /* # bytes of args + environ for exec() */
