Should be "flush here."

WTF!

You check for arguments like this:

if(argc != 2)

or:

if(argv[1] == NULL)

WTF!

You are assigning a pointer with the value 0x2F.

If it's then passed to pathconf() then KABOOM!

"result" is an int.  pathcomp() returns a long int.

You should either have declared "result" as a long int
or:

result = (int)pathconf(path,_PC_PATH_MAX)



Congrats.  In a few short lines you have created a huge mess.
