FYI: native JNI FileChannelImpl.size() implemented

[Mark Wielaard]

Hi,

The following implements the native JNI FileChannelImpl.size() method.
It is a simple copy/paste of the old FileDescriptor.getNativeLenght()
implementation.

2004-04-11  Mark Wielaard  <address@hidden>

       * native/jni/java-nio/gnu_java_nio_channels_FileChannelImpl.c
       (Java_gnu_java_nio_channels_FileChannelImpl_size): Implemented.

This solves a large number of mauve failures that depended on being able
to get the size of a file.

Cheers,

Mark
