[PATCH master 1/3] envfs: fix defaultenv_append_directory macro definition

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

 



defaultenv_append_directory is called as if it were a function and the
trailing semicolon can break parse of if-else statements. Wrap in do { }
while (0) to avoid this.
