Hello colleagues,
I want to get the name of the faile logically linked by another one, in an executable program; I don't want to use s "system ll"; are there any system call, any library to get this information?
Thanks
Enrico

Hi Enrico:
Have a look at 'readlink(2)'.
Consider:
# ls -l /tmp/f1 /var/tmp/f1
-rw-r----- 1 root sys 0 Nov 25 13:14 /tmp/f1
lrwxr-x--- 1 root sys 7 Nov 25 13:14 /var/tmp/f1 -> /tmp/f1
With perl:
# perl -le '$_=readlink($ARGV[0]);print if defined' /var/tmp/f1
...returns:
/tmp/f1
Regards!
