Re: Calling an ILE C Routine from ILE RPG (V7R2)

Did you download the source a long time back Patrick?

Either that, or it's the source from the readymade package in Debian 9, maybe. Anyway, I corrected that possible issue.

Because the feature that uses that parm was added some long time ago. You might want to consider updating your source to the later version.

I did, see other mail.

Just to clarify - any C code written to be multi-platform will always need a X'00' termination for strings unless: 1) The length is also passed as a separate parm or 2) This is a rare case where the C code uses a fixed length field.

I was trying to work towards 2), because the output of pw_rand is supposed to be always 64 characters.

If those circumstances do not apply then there is no way for it to know the length without some termination.

Thanks. Yes, I'm aware of that. From the comments to my original post I had the impression that there's some "magic" happening somewhere to have the buffer for pw_rand's answer filled with X'00' beforehand. Or at least have the first char in the buffer being X'00'. Apparently it is not, which is nicely reassuring my understanding of C so far.

Glad the termination sorted your problem for you.

It did not. :-( I'm sure I messed something up.
