Arguments

 

code

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

   Code specifying any one of the statistics to be written to
   SYS$OUTPUT or passed to an action routine for processing.
   The code argument is the address of a signed longword integer
   containing the statistic code. This is an optional argument. If
   the statistic code is omitted or is zero, statistics for values
   1, 2, and 3 are returned on one line.

   The following values are allowed for the code argument:

   Value Statistic

   0     Statistics for values 1, 2, and 3 are returned.
   1     Number of successful calls to LIB$GET_VM.
   2     Number of successful calls to LIB$FREE_VM.
   3     Number of bytes allocated by LIB$GET_VM but not yet
         deallocated by LIB$FREE_VM.
   4     Statistics for values 5, 6, and 7 are returned.
   5     Number of calls to LIB$GET_VM_PAGE.
   6     Number of calls to LIB$FREE_VM_PAGE.
   7     Number of VAX pages or Alpha pagelets allocated by LIB$GET_
         VM_PAGE but not yet deallocated by LIB$FREE_VM_PAGE.
 

user-action-procedure

   OpenVMS usage:procedure
   type:         procedure value
   access:       function call (before return)
   mechanism:    by value

   User-supplied action routine called by LIB$SHOW_VM. By default,
   LIB$SHOW_VM returns statistics to SYS$OUTPUT. An action routine
   is useful when you want to return statistics to a file or, in
   general, to any place other than SYS$OUTPUT. The routine returns
   either a success or failure condition value, which will be
   returned as the value of LIB$SHOW_VM.
 

user-specified-argument

   OpenVMS usage:user_arg
   type:         longword (unsigned)
   access:       read only
   mechanism:    by value

   A 32-bit value to be passed directly to the action routine
   without interpretation. That is, the contents of the argument
   list entry user-specified-argument are copied to the argument
   list entry for user-action-procedure.
