Where are the native linux methods in openjdk?

Question

I am trying to find native method implementation for linux:

private native int socketRead0(FileDescriptor fd,
                                   byte b[], int off, int len,
                                   int timeout)

I could not find it in Openjdk source files. I grepped all the files for "socketRead0" but it found only implementations for windows and solaris. Where is it?

Answer 1

socketRead0 implementation for Linux is defined in the Solaris version: SocketInputStream.c. This file includes net_util.h which in turn includes net_util_md.h.

net_util_md.h uses a #ifdef __linux__ directive to distinguish between Linux and Solaris
