Arguments
code
OpenVMS usage:quadword_signed
type: quadword integer (signed)
access: read only
mechanism: by reference
Code specifying any one of the statistics to be written to
SYS$OUTPUT or passed to an action routine for processing.
The code argument is the address of a signed quadword integer
containing the statistic code. This is an optional argument. If
the statistic code is omitted or is zero, statistics for values
1, 2, and 3 are returned on one line.
The following values are allowed for the code argument:
Value Statistic
0 Statistics for values 1, 2, and 3 are returned.
1 Number of successful calls to LIB$GET_VM_64.
2 Number of successful calls to LIB$FREE_VM_64.
3 Number of bytes allocated by LIB$GET_VM_64 but not yet
deallocated by LIB$FREE_VM_64.
4 Statistics for values 5, 6, and 7 are returned.
5 Number of calls to LIB$GET_VM_PAGE_64.
6 Number of calls to LIB$FREE_VM_PAGE_64.
7 Number of Alpha or I64 pagelets allocated by LIB$GET_VM_
PAGE_64 but not yet deallocated by LIB$FREE_VM_PAGE_64.
user-action-procedure
OpenVMS usage:procedure
type: procedure value
access: function call (before return)
mechanism: by value
User-supplied action routine called by LIB$SHOW_VM_64. By
default, LIB$SHOW_VM_64 returns statistics to SYS$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_64.
user-specified-argument
OpenVMS usage:user_arg
type: quadword (unsigned)
access: read only
mechanism: by value
A 64-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.
