[PATCH 02/19] wrapper.c: remove/unlink_or_warn: simplify, treat ENOENT as success

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ronnie Sahlberg <sahlberg@xxxxxxxxxx>

Simplify the function warn_if_unremovable slightly. Additionally, change
behaviour slightly. If we failed to remove the object because the object
does not exist, we can still return success back to the caller since none of
the callers depend on "fail if the file did not exist".
