Arguments

 

termtable-address

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

   Specifies the address of the TERMTABLE entry for the desired
   terminal. The termtable-address argument is the address of an
   unsigned longword that contains the address of the terminal
   capabilities table (TERMTABLE).

   The TERMTABLE address is returned by SMG$INIT_TERM_TABLE or
   SMG$INIT_TERM_TABLE_BY_TYPE.
 

request-code

   OpenVMS usage:longword_signed
   type:         longword (signed)
   access:       read only
   mechanism:    by reference

   Longword constant of the form SMG$K_code, where code is the name
   of the desired capability field. The request-code argument is
   the address of a signed longword that contains the request code.
   The SMG$K_code constants can be found in the library supplied by
   OpenVMS, $SMGTRMPTR.
 

maximum-buffer-length

   OpenVMS usage:longword_signed
   type:         longword (signed)
   access:       read only
   mechanism:    by reference

   Maximum length of the buffer into which the requested capability
   data is written. The maximum-buffer-length argument is the
   address of a signed longword that contains the maximum number
   of bytes that can be written into the buffer.
 

return-length

   OpenVMS usage:longword_signed
   type:         longword (signed)
   access:       write only
   mechanism:    by reference

   Receives the number of bytes actually written into the buffer.
   The return-length argument is the address of a signed longword
   into which is written the number of bytes transferred into the
   buffer.
 

capability-data

   OpenVMS usage:unspecified
   type:         unspecified
   access:       by reference, array reference
   mechanism:    0

   Address of the first byte of the buffer which is to receive
   the capability data. The capability-data argument contains the
   address of the buffer.
 

input-argument-vector

   OpenVMS usage:vector_longword_unsigned
   type:         longword (unsigned)
   access:       read only
   mechanism:    by reference, array reference

   Address of a list of longwords used for capabilities that require
   a variable number of arguments, and for those that require
   substitution or arithmetic operations on an argument. The input-
   argument-vector argument is the address of an array of unsigned
   longwords that contains capability arguments. The first longword
   must contain the number of arguments that follow.
