NAME

sys.ops - System Interaction Dynops

DESCRIPTION

Operations that allow the user to interact with the system.

gmtime(out STR, in INT)

Take the integer, which represents GMT epoch-seconds, and turn it into a formatted string.

localtime(out STR, in INT)

Take the integer, which represents GMT epoch-seconds, and turn it into a formatted string. The time is adjusted to localtime before formatting.

decodetime(out PMC, in INT)

Take the integer, which represents GMT epoch-seconds, and return an Array PMC which represents the decoded time. The array elements are (include "tm.pasm" for the constants):

0, .TM_SEC

Seconds (0-60)

1, .TM_MIN

Minutes (0-59)

2, .TM_HOUR

Hours (0-23)

3, .TM_MDAY

Day of month (1-31)

4, .TM_MON

Month of year (1-12) (Note, actual month, not month - 1)

5, .TM_YEAR

Year (note, actual year. The year 2004 comes back as 2004, not 104)

6, .TM_WDAY

Day of week. Sunday is day 0

7, .TM_YDAY

Day of year (0-365)

8, .TM_ISDST

Daylight savings/summer time in effect

Timezone name will be GMT and offset will be 0, since the time is taken and decoded as GMT.

decodelocaltime(out PMC, in INT)

Take the passed in integer, which represents GMT epoch-seconds, and return an array as in decodetime. The time is first shifted to localtime before decoding.

sysinfo(out STR, in INT)

Return system information. The values it returns depends on what you ask. They are:

PARROT_INTSIZE The size of a platform integer

PARROT_FLOATSIZE The size of a platform float

PARROT_POINTERSIZE The size of a platform pointer (Largest possible data pointer)

PARROT_INTMAX The maximum value of a platform integer

PARROT_INTMIN The minimum value of a platform integer

sysinfo(out INT, in INT)

Return system information. The values it returns depends on what you ask. They are:

PARROT_OS The OS name

This is something like "OS X", "MacOS", "Windows", or "VMS".

PARROT_OS_VERSION The OS version string

This is the current (hopefully) OS Version. For OSes that have plain version numbers it will be the version number. For OSes that name their versions, it will be the version name.On HP/UX, this may be something like 11.2, while on Windows it may be "95", "98", "2000", "NT", "ME", or "XP".

PARROT_OS_VERSION_NUMBER The OS version number string

On OSes that don't name themselves, this will be the same as what's returned in the OS version string. On OSes that do name themselves, this will be a more specific version number. In all cases it is OS dependent.

CPU_ARCH The CPU architecture

The name of the CPU family, such as "VAX", "Alpha", "PPC", or "x86".

CPU_TYPE The CPU model

The model name of the current system's CPU. This is something like "EV68", "Athlon", or "Pentium III".

Note that some of these values may be set at Parrot compile time, rather than at runtime, if the system has no reliable way to fetch the data dynamically, or if there is no way the value can change. Also, the value returned may be somewhat misleading--Parrot running under a VirtualPC window will report "Windows" as its OS and "x86" as its CPU, even if it's really running on an OS X system.
