[Nagios-devel] Erroneous use of getcwd on lib/nspath.c
[Nagios-devel] Erroneous use of getcwd on lib/nspath.c
Accordingly to manpages and some home made tests, getcwd returns NULL
when an error occurs, not a value and use macro
MAX_PATH, not a fixed size of 4096.
Also we don't need to make sizeof(path) - 1 when calling getcwd.
Quoting manpage:
"The size argument is the size, in bytes, of the array referenced by
buf."
Is it sounds resonable?
Comments?
