smc_run - start a TCP socket program with the capability to use SMC as networking protocol

smc_run  starts a program specified as argument with its parameters, allowing to use the SMC protocol for
       program-used TCP socket connections.
       The script specifies libsmc-preload.so as a preload shared library for the Linux program loader, and  may
       adjust  transmit  and  receive  buffer  sizes  to  SIZE by setting socket options SO_RCVBUF and SO_SNDBUF
       respectively.  SIZE can be specified in Bytes or using metric prefixes k and m, e.g.  8k...1024k/1m.
       The preload library libsmc-preload.so intercepts a few TCP  socket  calls  and  triggers  the  equivalent
       execution through SMC.
       Note:  If  it is not possibile to use smc_run, the libsmc-preload.so may be installed as apreload library
       via environment variable LD_PRELOAD. Use  environment  varibles  SMC_SNDBUF  and  SMC_RCVBUF  to  request
       specific transmit and receive buffer sizes respectively. Supports metric prefixes k and m.

       The following options can be specified:

       -d     Display additional diagnostic messages during the program execution.

       -h     Display a brief usage information.

       -rSIZE
              Request receive buffer size SIZE.
              Notes:

              • May be overridden by the application.

              • Increases net.core.rmem_max if necessary.

       -tSIZE
              Request transmit buffer size SIZE.
              Notes:

              • May be overridden by the application.

              • Increases net.core.wmem_max if necessary.

       -v     Display version information.

       On  success,  the  smc_run  command returns 0.  If an error occurs smc_run writes a message to stdout and
       completes with a return code other than 0.
