Arguments

 

streams

   OpenVMS usage:longword_unsigned
   type:         longword (unsigned)
   access:       read only
   mechanism:    by reference
   Maximum number of streams that the symbiont is to support. The
   streams argument is the address of a longword containing this
   number, which must be in the range of 1 to 16. If you do not
   specify streams, a default value of 1 is used. Thus, by default,
   a user-modified symbiont supports one stream, which is to say
   that it is a single-threaded symbiont.

   A stream (or thread) is a logical link between a print execution
   queue and a printing device. When a symbiont process can accept
   simultaneous links to more than one queue, that is, when it can
   service multiple queues simultaneously, the symbiont is said to
   be multithreaded.
 

bufsiz

   OpenVMS usage:longword_unsigned
   type:         longword (unsigned)
   access:       read only
   mechanism:    by reference
   Maximum buffer size in bytes that the print symbiont is to use
   for output operations. The bufsiz argument is the address of a
   longword containing the specified number of bytes.

   The print symbiont actually uses a buffer size that is the
   smaller of: (1)  the value specified by bufsiz or (2) the
   system parameter MAXBUF. If you do not specify bufsiz, the print
   symbiont uses the value of MAXBUF.

   The print symbiont uses this size limit only for output
   operations. Output operations involve the placing of processed or
   formatted pages into a buffer that will be passed to the output
   routine.

   The print symbiont uses the value specified by bufsiz only as
   an upper limit; most buffers that it writes will be smaller than
   this value.
 

worksiz

   OpenVMS usage:longword_unsigned
   type:         longword (unsigned)
   access:       read only
   mechanism:    by reference
   Size in bytes of a work area to be allocated for the use of user
   routines. The worksiz argument is the address of a longword
   containing this size in bytes. If you do not specify worksiz,
   no work area is allocated.

   A separate area of the specified size is allocated for each
   active symbiont stream.
 

maxqios

   OpenVMS usage:longword_unsigned
   type:         longword (unsigned)
   access:       read only
   mechanism:    by reference

   Specifies the maximum number of outstanding $QIOs that a print
   symbiont stream using the LAT protocol may generate. Set symbiont
   process quotas large enough to handle the maximum number of QIOs
   multiplied by the number of streams, using a number between 2 and
   32. For normal printing capabilities, the suggested quota is 10;
   for high-speed printing, use a larger number.
 

options

   OpenVMS usage:longword_unsigned
   type:         longword (unsigned)
   access:       read only
   mechanism:    by reference

   Longword bit vector that specifies the LAT protocal option using
   the PSM$M_LAT_PROTOCOL symbolic value. Note that using the LAT_
   PROTOCOL option carries the following restrictions:

   o  Replacement of the output and job completion routines will be
      overridden

   o  Output device must be a LAT device
