Thread: sacio: use of nerr parameter in rsac...() functions

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)

Best regards Peter
