Gamma™ : Version 6.4
	QNX 4

`qnx_osinfo`

qnx_osinfo — returns a class very similar to QNX 4 struct_osinfo.

Syntax

qnx_osinfo (node)

Arguments

node: The node to query.

Returns

An instance of the class Osinfo, or nil on failure.

Description

This function returns a class very similar to the QNX 4 struct _osinfo. It is currently only available in QNX 4. The instance variables of this class are:

bootsrc a single integer value that is the ASCII value for the character 'F' for floppy, 'H' for hard, or 'N' for network. Use char() function to convert.

cpu processor type, typically given as the last 3 digits (386,486,586,686,etc.)

cpu_speed a measure of the CPU speed using a 16-bit algorithm. A classic PC/XT is 96. A 133MHz Pentium is approx. 18000-19000.

fpu the floating point processor type given as the last 3 digits of the chip (387,487,587,687,etc.)

freememk free memory in the system

machine machine name

max_nodes the number of nodes you are licensed for

nodename logical node numberof this cpu

num_handlers maximum number of interrupt handlers

num_names maximum number of names

num_procs mamimum number of processes (programs + virtual curcuits + proxies)

num_sessions maximum number of sessions

num_timers maximum number of timers

pidmask process ID bit mask

release a single number that is the ASCII equivalent of the release letter. Use char() function to convert.

reserve64k Relocation offset

sflags System flags, see below

tick_size tick size, in microseconds

timesel segment in which the time is kept

totmemk total memory (kB) in the system

version the QNX 4 version number * 100

The following system flags are available: nil

_PSF_PROTECTED The system is running in protected mode

_PSF_NDP_INSTALLED An 80x87 numeric processor is installed

_PSF_EMULATOR_INSTALLED An 80x87 emulator is running

_PSF_EMU16_INSTALLED The 16-bit 80x87 emulator is running

_PSF_EMU32_INSTALLED The 32-bit 80x87 emulator is running

_PSF_APM_INSTALLED Advanced Power Management is running in the BIOS of this system

_PSF_32BIT_KERNEL This system is running with a 32 bit kernel

_PSF_PCI_BIOS This system has a PCI BIOS

_PSF_32BIT Proc32 is running

_PSF_RESERVE_DOS The lower 640k is reserved for DOS

_PSF_RESERVE_DOS32 ???
