qnx_osinfo

Arguments

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 ???
