getcmd

	getcmd(command_buffer.i1a.r, status.i2.r [,buffer_length.i2.r])

	This routine retrieves a command buffer queued to the task at the
	TIME it was requested (by a call to the 'chgpgm' routine).  The
	command buffer is stored in the console common, CNSCOM, until it is
	retrieved by a call to this routine.  This routine must be called
	during the initialization phase of application execution ('intype'
	routine returns an interrupt type of INTINI) or this information
	will be lost.

	command_buffer	user buffer to receive the command line
                       Command buffers that contain binary floating-point
                       values are to be preserved in the format
                       expected by the VMS version of applications.
                       Generaly, that will mean DEC format and that
                       Linux applications will need to convert
                       into IEEE.
	status		returned status of command buffer retrieval
			(CLIB_OK -> successful transfer of command line,
			 CLIB_GETCMD_NOBUFFER -> no command line buffer
						 queued for this task)
	[buffer_length]	length of command line buffer to return.  Defaults
			to 80 bytes.  Maximum length is CMD_LIN_SIZ.
			(default is NULL)
