/*
* TTCP * * Test TCP connection. Makes a connection on port 5001 * and transfers fabricated buffers or data copied from stdin. * * Usable on 4.2, 4.3, and 4.1a systems by defining one of * BSD42 BSD43 (BSD41a) * Machines using System V with BSD sockets should define SYSV. * * Modified for operation under 4.2BSD, 18 Dec 84 * T.C. Slattery, USNA * Minor improvements, Mike Muuss and Terry Slattery, 16-Oct-85. * Modified in 1989 at Silicon Graphics, Inc. * catch SIGPIPE to be able to print stats when receiver has died * for tcp, don't look for sentinel during reads to allow small transfers * increased default buffer size to 8K, nbuf to 2K to transfer 16MB * moved default port to 5001, beyond IPPORT_USERRESERVED * make sinkmode default because it is more popular, * -s now means don't sink/source * count number of _read/_write system calls to see effects of * blocking from full socket buffers * for tcp, -D option turns off buffered writes (sets SO_NODELAY sockopt) * buffer alignment options, -A and -O * print stats in a format that's a bit easier to use with grep & awk * for SYSV, mimic BSD routines to use most of the existing timing code * * Distribution Status - * Public Domain. Distribution Unlimited. */
