See lib/cycle-check.c. - - RM is careful to avoid forming full file names whenever possible. - A full file name is formed only when it is about to be used -- e.g. - in a diagnostic or in an interactive-mode prompt. - - RM minimizes the number of lstat system calls it makes. On systems - that have valid d_type data in directory entries, RM makes only one - lstat call per command line argument -- regardless of the depth of - the hierarchy. */ +/* Initially written by Paul Rubin, David MacKenzie, and Richard Stallman. + Reworked to use chdir and avoid recursion, and later, rewritten + once again, to use fts, by Jim Meyering. */ #include <config.h> #include <stdio.h> @@ -358,7 +335,7 @@ main (int argc, char **argv) } size_t n_files = argc - optind; - char const *const *file = (char const *const *) argv + optind; + char **file = argv + optind; if (prompt_once && (x.recursive || 3 < n_files)) { @@ -370,7 +347,8 @@ main (int argc, char **argv) if (!yesno ()) exit (EXIT_SUCCESS); } - enum RM_status status = rm (n_files, file, &x); + + enum RM_status status = rm (file, &x); assert (VALID_STATUS (status)); exit (status == RM_ERROR ?
