Subject: [PATCH] posix: Fix attribute access mode on getcwd [BZ #27476]
|
||
|
|
|
||
|
|
There is a GNU extension that allows to call getcwd(NULL, >0). It is
|
||
|
|
described in the documentation, but also directly in the unistd.h
|
||
|
|
header, just above the declaration.
|
||
|
|
|
||
|
|
Therefore the attribute access mode added in commit 06febd8c6705
|
||
|
|
is not correct. Drop it.
