Function readlink_stat

flist.c:217–244

Stat either a symlink or its referent, depending on the settings of * copy_links, copy_unsafe_links, etc. Returns -1 on error, 0 on success. * * If path is the name of a symlink, then the linkbuf buffer (which must hold * MAXPATHLEN chars) will be set to the symlink's target string. * * The stat structure pointed to by stp will contain information about the * link or the referent as approp

 * The stat structure pointed to by stp will contain information about the
 * link or the referent as appropriate, if they exist. */
