Hi all

I'm hoping that someone can shed some light upon the the usage of the
nerr parameter in the rsac...() function

Reading the SAC manual, section :"SAC Reading and Writing Routines", I
got the impression that this parameter could be used to check the
success/failure to read a file (0 - success, else failure), yet when I
try to read a non-valid SAC file (i.e. which should fail) nerr is 0 upon
return, which later in my code causes an annoying segmentation fault as
I have no other way to check that the file were properly read.

Now, have I perhaps misunderstood the usage of nerr or may this be a bug
worth reporting?

(I'm runing SAC-101.6a, built 10/14/2014 from source on Linux)
