4 Invoking gjnih

The gjnih program is used to generate JNI header files from class files. Running it is equivalent to running gcjh -jni.

-stubs

This causes gjnih to generate stub files instead of header files. By default the stub file will be named after the class, with a suffix of `.c'.

-jni

This option specifies the default behavior which is to generate a JNI header or stub.

-force

This option forces gjnih to write the output file.

-old

This option is accepted but ignored for compatibility.

-trace

This option is accepted but ignored for compatibility.

-J option

This option is accepted but ignored for compatibility.

-add text

Inserts text into the class body. This is ignored in by gjnih.

-append text

Inserts text into the header file after the class declaration. This is ignored in by gjnih.

-friend text

Inserts text into the class as a friend declaration. This is ignored by gjnih.

-prepend text

Inserts text into the header file before the class declaration. This is ignored in by gjnih.
