Hello All,
I was running strace over ifconfig command and part of the output is shown below . I notice something strange in the length of the buffer address of the read syscall . Can somebody throw some light on this ?
open("/proc/net/if_inet6", O_RDONLY) = 10
fstat64(10, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7ce8000
read(10, "fe80000000000000021676fffe79ceb2"..., 1024) = 108
write(1, " inet6 addr: fe80::216:"..., 61 inet6 addr: fe80::216:76ff:fe79:ceb2/64 Scope:Link
) = 61
read(10, "", 1024) = 0
read(10, "", 1024) = 0
close(10) = 0
