Then your RPG prototype should be 10A, not a pointer with options(*string).

Your original typedefs were correct. Having char* typedefs, and then secretly requiring the caller to set up blank-filled values doesn't seem very friendly.

I think a better alternative would be to allow all your callers to pass null-terminated strings, and have your procedure get the data in the right form.

D proc pi
D libP * value options(*string)
D logMessageP * value options(*string)

D lib s 10a
D logMessage s 2048a varying
lib = %str(libparm);
logMessage = %str(logMessageP);
