LogWarn() (and the others like it) are printf-alikes, so they need a
format parameter. It would be called like this:
LogWarn(COMPONENT_NFS_V4, "%s", errstr);
But, you don't need the errstr at all, you can just call like this:
LogWarn(COMPONENT_NFS_V4, "Invalid map: %s: %s", clue, line);

Hi,
I’m trying to call your logging as follows:
sprintf(errstr, "Invalid map: %s: %s", clue, line);
LogWarn(COMPONENT_NFS_V4, errstr);
I’m getting a segfault in LogWarn.
Program received signal SIGSEGV, Segmentation fault.

The traceback is below. I’m investigating, but any advice is welcome.
Thanks.
