Re: Calling C from RPG: what am I doing wrong?

James,

options(*string) causes RPG to make a copy of your variable and add a x'00' to the end, then pass that temporary copy. You cannot use options(*string) for an output (or in/out) parameter.

Instead, consider passing buffy as an alphanumeric field (NOT a pointer). If it needs to be null-terminated on the RPG side, then use the %str() BIF to null-terminate it before you pass it.

Thanks. That's what I was afraid of.
