If there are better alternatives I'd be happy to use them instead. But we already use PATH_MAX elsewhere in the tools, so this might be a wider-ranging cleanup than you think. The original impetus for this change was due to bugchecks applied in some cases by glibc's realpath() implementation. But actually is realpath() deprecated anyway? -- Keir On 4/4/08 15:17, "Samuel Thibault" <samuel.thibault@xxxxxxxxxxxxx> wrote: > 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.
