I'm looking at the IBM-supplied copybook for the JNI APIs in QSYSINC. It defines jvalue as follows:
midrange.com
D jvalue DS QUALIFIED
D BASED(jvalue_P)
D z LIKE(jboolean)
D b LIKE(jbyte)
D c LIKE(jchar)
D s LIKE(jshort)
D i LIKE(jint)
D j LIKE(jlong)
D f LIKE(jfloat)
D d LIKE(jdouble)
D l LIKE(jint)
Is this correct? The reason I ask is that when I use JNI on FreeBSD from C
programs, the jvalue definition looks like this:
typedef union jvalue {
jboolean z;
jbyte b;
jchar c;
jshort s;
jint i;
jlong j;
jfloat f;
jdouble d;
jobject l;
} jvalue;
The big difference is that the RPG definitions are a data structure. The
C definitions are a union!
Shouldn't the RPG definition look like the following?
D jvalue DS QUALIFIED
D BASED(jvalue_P)
D z LIKE(jboolean)
D overlay(jvalue:1)
D b LIKE(jbyte)
D overlay(jvalue:1)
D c LIKE(jchar)
D overlay(jvalue:1)
D s LIKE(jshort)
D overlay(jvalue:1)
D i LIKE(jint)
D overlay(jvalue:1)
D j LIKE(jlong)
D overlay(jvalue:1)
D f LIKE(jfloat)
D overlay(jvalue:1)
D d LIKE(jdouble)
D overlay(jvalue:1)
D l LIKE(jint)
D overlay(jvalue:1)
Or does JNI work differently on the System i than it does on FreeBSD? ( or
am I just nuts? )
