Problems with qnx_osinfo() and freememk member of _osinfo structure |

| Issue |
The freememk member of the _osinfo structure has
unsigned short type. Thus qnx_osinfo() returns
incorrect value of free memory if its size is
more than 64M.
Is there another way to get free memory size?
|
| Solution |
Use freepmem instead.
Here's the description of all the fields:
short unsigned cpu_speed
A PC is around 96.
short unsigned num_procs
Max number of processes.
short unsigned tick_size
Tick size, in microsecond units.
short unsigned version
Version number of QNX * 100.
short unsigned timesel
Segment in which the time is kept.
short unsigned totmemk
Use totpmem instead.
short unsigned freememk
Use freepmem instead.
char release
Release letter.
long sflags
System flags, as defined below.
long nodename
Logical node number of this cpu.
long cpu
Processor type 386, 486, 586, 686, ...
long fpu
Floating-point unit 287, 387, 487. 587, 687.
char machine[16]
Machine name. Examples include EISA, PCI, PS/2, and ziatech.
char bootsrc
'F' - floppy 'H' - hard disk 'N' - network
short unsigned num_names
Maximum number of names.
short unsigned num_timers
Maximum number of timers.
short unsigned num_sessions
Maximum number of sessions.
short unsigned num_handlers
Maximum number of interrupt handlers.
short unsigned reserve64k
Relocation offset (see -R option to Proc).
short unsigned max_nodes
Number of nodes you are licensed for.
short unsigned proc_freemem
Not used.
short unsigned fd_freemem
Not used.
