Except if fd refers to a pipe, in which case writes of up to PIPE_MAX will be atomic. Also, I just noticed another problem. What if the fd does not refer to an actual file, but a non-seekable file system object (named pipe, domain socket, ...). Will the lseek work on that? I have no idea. But, I think you're implementing a broken API to save a couple of lines of code. (btw, you may want to know that pwrite() on O_APPEND descriptors basically ignores the offset argument, and always does an append). https://reviews.llvm.org/D25783 _______________________________________________ lldb-commits mailing list lldb-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits
