REX(3R)                 COMMAND REFERENCE                 REX(3R)



NAME
     rex - remote execution protocol

SYNOPSIS
     #include <sys/ioctl.h>
     #include <rpcsvc/rex.h>

DESCRIPTION
     This server executes commands remotely.  The working
     directory and environment of the command can be specified
     and standard input and output of the command arbitrarily
     redirected.  An option is provided for interactive I/O for
     programs that expect to be running on terminals; note that
     this service is only provided with the TCP transport.

          procs:
               REXPROC_START
                    Takes rex_start structure, starts a command
                    executing, and returns a rex_result structure.
               REXPROC_WAIT
                    Takes no arguments, waits for a command to finish
                    executing, and returns a rex_result structure.
               REXPROC_MODES
                    Takes a rex_ttymode structure, and sends the tty modes.
               REXPROC_WINCH
                    Takes a ttysize structure, and sends window size
                    information.
