stimulate ls -l
Hi. If anyone can help me with ls –l I appreciate that. I've written program in c to stimulate ls -l.
it's works well except the link. I need to print out the line like this
lrwxrwxrwx 1 admin admin 11 Feb 27 19:08 figC.18 -> ipc/fifo1.c.
but it’s just print lrwxrwxrwx 1 admin admin 11 Feb 27 19:08 figC.18. I need to make my program print the link also.
Thanks for your help

I used this part in my program
char targetName[PATH_MAX + 1];
if( readlink( pathName, targetName, PATH_MAX ) != -1 )
{
printf( "\t%s -> %s\n", pathName, targetName );
}
else
printf( "\t%s -> (invalid symbolic link!)\n", pathName );
and it worked with me.
Thanks so much for your time phoffric !!

Glad you found it helpful.
Also, look at http://www.ibm.com/developerworks/aix/library/au-unix-readdir.html :
•S_ISBLK(mode) -- Is this a block special file? (usually a block-based device of some sort)
•S_ISCHR(mode) -- Is this a character special file? (again, usually a character-based device of some sort)
•S_ISDIR(mode) -- Is this a directory?
•S_ISFIFO(mode) -- Is this a pipe or FIFO special file?
•S_ISLNK(mode) -- Is this a symbolic link?
•S_ISREG(mode) -- Is this a regular file?
