Yes I changed to Value for the pass and ccsid parms. Please note that the IBM Manual on line says the ccsid should be 10u which cant be correct as I need to pass a -1 to get the proper ccsid.
signed and unsigned occupy the same amount of storage. How it is interpreted depends on the definition in the called function.
You're correct that it can't really be unsigned but that doesn't stop the prototype being defined that way. The caller will treat the value as unsigned but the callee can treat it as signed if it chooses.
Unix APIs are full of this sort of rubbish. A number of the socket functions return unsigned values and then define a return code of -1 as an error. Duh! Note this is not an OS/400 issue. This is just dumb Unix behaviour.
Please clarify this statement below from the manual. What do they mean by Omissable, that its required to exist in the prototype but does not have to be used? "This parameter is optional for QSYRLSPH API and is omissable for the QsyReleaseProfileHandle API"
midrange.com
In RPG IV terms:
Optional means define the prototype using OPTIONS(*NOPASS)
Omissable means define the prototype using OPTIONS(*OMIT)
Further, optional means you don't have to pass anything at all;
omissable means you must pass something but a NULL pointer is allowed
and will be treated as if you passed nothing.
