ls -l implementation in c++

[FuzZy2006]

which is the c++ code that would do the same thing that the ls -l command does?

[supirman]

glibc filesystem interface (http://www.gnu.org/software/libc/manual/html_node/File-System-Interface.html#File-System-Interface)

- run strace ls -al
- and look at the output:



fstat64(1, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 0), ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7c63000
write(1, "000_0198.jpg\t cv\t\t\t\t\t "..., 139000_0198.jpg


Prior to writing the output it did a call to 'fstat64'

- gather info on fstat:



e@lap:~$ whatis fstat
fstat (2) - get file status


And now the most vital part:


man fstat


And now it is only a matter of formatting. i wish everything in life was this easy ;)
