Guys,
I'm doing signal handling in Perl. I'm trying to catch ^C signal inside the script.
There two scripts : one shell script and one perl script.
The shell script calls the perl script.
For e.g. shell script a.sh and perl scipt sig.pl.
Shell script a.sh looks something like this :... (6 Replies)

Hello all,

ATAPICAM(4) BSD Kernel Interfaces Manual ATAPICAM(4)NAME
atapicam -- CAM XPT (transport) module for ATAPI devices
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device scbus
device ata
device atapicam
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
atapicam_load="YES"
DESCRIPTION
The ATAPI/CAM module allows ATAPI devices (CD-ROM, CD-RW, DVD drives, floppy drives such as Iomega Zip, tape drives) to be accessed through
the SCSI subsystem, cam(4).
ata(4) and scbus(4) must be configured in the kernel as well. The SCSI target drivers (cd(4), da(4), or st(4)) can then be used to access
the devices. The generic passthrough device, pass(4), can also be used to send SCSI commands directly to the devices through the CAM API.
A separate CAM bus is created for each ATA bus in the system. On each of these buses, target ID 0 is assigned to the master device, and ID 1
is assigned to the slave (provided they are ATAPI devices).
IMPLEMENTATION NOTES
Some SCSI commands are intercepted by the driver, and undergo special processing in order to work around limitations of ATAPI devices. Such
limitations can be consequences of the ATAPI specification. For example, ATAPI devices do not implement the 6-byte versions of MODE_SELECT,
MODE_SENSE, READ, or WRITE. They can also be common bugs, such as hanging when queried for extended INQUIRY information.
EXAMPLES
device ata
device atapicam
device scbus
device cd
device pass
Add the atapicam driver to the kernel.
camcontrol devlist
Print the list of all devices available through CAM.
mount -t cd9660 /dev/cd0 /mnt
Mount a CD-ROM from an ATAPI CD-ROM drive (the command above assumes that the ATAPI drive is the only CD-ROM unit).
SEE ALSO ata(4), cam(4), scsi(4), atacontrol(8), camcontrol(8)HISTORY
The ATAPI/CAM driver first appeared in FreeBSD 4.8 and FreeBSD 5.0.
AUTHORS
The ATAPI/CAM driver was written by Thomas Quinot <thomas@FreeBSD.org>.
BUGS
atapicam and ATAPI-specific target drivers (acd(4), ast(4), and afd(4)) can be configured in the same kernel. Simultaneous access to the
same device through the SCSI generic drivers and the ATAPI-specific drivers may cause problems and is strongly discouraged.
