Great Link and support refrence documentations for NetBSD, AIX and Solaris multi support. Featuring from Installation, configurations and Troubleshoot. A must see.
Guys,
May i know how can we de reference the code reference variable.?
my $a = sub{$a=shift;$b=shift;print "SUM:",($a+$b),"\n";};
print $a->(4,5);
How can we print the whole function ?
Please suggest me regarding this.
Thanks for your time :)
Cheers,

cdtoc(4) File Formats cdtoc(4)NAME
cdtoc - CD-ROM table of contents file
DESCRIPTION
The table of contents file, .cdtoc, is an ASCII file that describes the contents of a CD-ROM or other software distribution media. It
resides in the top-level directory of the file system on a slice of a CD-ROM. It is independent of file system format, that is, the file
system on the slice can be either UFS or HSFS.
Each entry in the .cdtoc file is a line that establishes the value of a parameter in the following form:
PARAM=value
Blank lines and comments (lines preceded by a pound-sign, ``#'') are also allowed in the file. Parameters are grouped by product, with the
beginning of a product defined by a line of the form:
PRODNAME=value
Each product is expected to consist of one or more software packages that are stored together in a subdirectory on the distribution media.
There can be any number of products described within the file. There is no required order in which the parameters must be specified, except
that the parameters must be grouped by product and the PRODNAME parameter must appear first in the list of parameters for each product
specified. Each parameter is described below. All of the parameters are required for each product.
PRODNAME The full name of the product. This must be unique within the .cdtoc file and is preferably unique across all possi-
ble products. This value may contain white space. The length of this value is limited to 256 ASCII characters;
other restrictions may apply (see below).
PRODVERS The version of the product. The value can contain any combination of letters, numbers, or other characters. This
value may contain white space. The length of this value is limited to 256 ASCII characters; other restrictions may
apply (see below).
PRODDIR The name of the top-level directory containing the product. This name should be relative to the top-level directory
of the distribution media, for example, Solaris_2.6/Product. The number of path components in the name is limited
only by the system's maximum path name length, which is 1024 ASCII characters. Any single component is limited to
256 ASCII characters. This value cannot contain white space.
The lengths of the values of PRODNAME and PRODVERS are further constrained by the fact that the initial install programs concatenate these
values to produce the full product name. For unbundled products the combined length of the values of PRODNAME and PRODVERS must not exceed
256 ASCII characters.
When you install OS services with Solstice Host Manager, directories for diskless clients are created by constructing names derived from a
concatenation of the values of PRODNAME, PRODVERS, and client architecture, for example, /export/exec/Solaris_2.x_sparc.all/usr/platform.
The length of the component containing the product name and version must not exceed 256 ASCII characters. Thus, for products corresponding
to bundled OS releases (for example, Solaris 2.4), the values of PRODNAME and PRODVERS are effectively restricted to lengths much less than
256.
The initial install programs use the value of the PRODDIR macro in the .cdtoc file to indicate where packages can be found.
EXAMPLES
Example 1: Sample of .cdtoc file.
Here is a sample .cdtoc file:
#
# .cdtoc file -- Online product family CD
#
PRODNAME=Online DiskSuite
PRODVERS=2.0
PRODDIR=Online_DiskSuite_2.0
#
PRODNAME=Online Backup
PRODVERS=2.0
PRODDIR=Online_Backup_2.0
This example corresponds to the following directory layout on a CD-ROM partition:
/.cdtoc
/Online_DiskSuite_2.0
./SUNWmddr.c
./SUNWmddr.m
./SUNWmddu
/Online_Backup_2.0
./SUNWhsm
The bundled release of Solaris 2.6 includes the following .cdtoc file:
PRODNAME=Solaris
PRODVERS=2.6
PRODDIR=Solaris_2.6/Product
This file corresponds to the following directory layout on slice 0 of the Solaris 2.6 product CD:
/.cdtoc
/Solaris_2.6/Product
./SUNWaccr
./SUNWaccu
./SUNWadmap
.
.
.
./SUNWutool
