Ignoring other considerations makes it impossible to give you a useful answer.
- Have you included <string.h>? If not, what function prototype did you supply for strncpy(), if any?
- Have you included <sys/types.h>?
- How is a declared?
- How is c declared?
- What programming environment are you using?

Can someone help me out?

Hi,
There are some bewildering sizeof() questions I have in my mind. Could anyone shed some light on this?
int main() {
printf("%d\n", sizeof(main)); // Ans: 1
}
That is, the sizeof() a function identifier though it is treated internally as a pointer gives 1 byte always, why?

SYNOPSIS
rescan-scsi-bus.sh [options] [host [host ...]]
OPTIONS
-a, --alltargets
scan all targets, not just currently existing [default: disabled]
-d enable debug [default: 0]
-l activates scanning for LUNs 0--7 [default: 0]
-L NUM activates scanning for LUNs 0--NUM [default: 0]
-w, --wide
scan for target device IDs 0--15 [default: 0--7]
-c enables scanning of channels 0 1 [default: 0 / all detected ones]
-r, --remove
enables removing of devices [default: disabled]
-f, --flush
flush failed multipath devices [default: disabled]
-i, --issue-lip
issue a FibreChannel LIP reset [default: disabled]
-u, --update
look for existing disks that have been remapped
-s, --resize
look for resized disks and reload associated multipath devices, if applicable
--forcerescan
rescan existing devices
--forceremove
remove and readd every device (DANGEROUS)
--nooptscan
don't stop looking for LUNs is 0 is not found
--color
use coloured prefixes OLD/NEW/DEL
--hosts=LIST
scan only host(s) in LIST
--channels=LIST
scan only channel(s) in LIST
--ids=LIST
scan only target ID(s) in LIST
--luns=LIST
scan only lun(s) in LIST
--sync, --nosync

--reportlun2
tell kernel to try REPORT_LUN even on SCSI2 devices
--largelun
tell kernel to support LUNs > 7 even on SCSI2 devs
--sparselun
tell kernel to support sparse LUN numbering
Host numbers may thus be specified either directly on cmd line (deprecated) or or with the --hosts=LIST parameter (recommended).
LIST: A[-B][,C[-D]]... is a comma separated list of single values and ranges (No spaces allowed.)
