[Xen-devel] Re: Use PATH_MAX for pathname char arrays.

[Samuel Thibault <samuel.thibault@xxxxxxxxxxxxx>]

Hello,

Using PATH_MAX is not a good idea: POSIX says that that definition
is facultative, in case the system does not impose any limit on path
length.  Some systems may also set PATH_MAX to a quite high value, and
we would hence consume a lot of stack.

Samuel
