If the specified - * object is a directory, it will recursively remove the directory - * and everything underneath it. It assumes that it has privilege - * to remove everything that it tries to remove. If rmobj() encounters - * any problems, and errmsg is not NULL, errmsg is set to point to a - * string explaining the error. - * - * DETAILED DESCRIPTION - * Allocate space for the directory and its contents - * Open the directory to get access to what is in it - * Loop through the objects in the directory: - * If the object is not "." or "..": - * Determine the file type by calling lstat() - * If the object is not a directory: - * Remove the object with unlink() - * Else: - * Call rmobj(object) to remove the object's contents - * Determine the link count on object by calling lstat() - * If the link count >= 3: - * Remove the directory with unlink() - * Else - * Remove the directory with rmdir() - * Close the directory and free the pointers - * - * RETURN VALUE - * If there are any problems, rmobj() will set errmsg (if it was not - * NULL) and return -1. Otherwise it will return 0. - * - ************************************************************/ -#include <errno.h> /* for errno */ -#include <stdio.h> /* for NULL */ -#include <stdlib.h> /* for malloc() */ -#include <string.h> /* for string function */ -#include <limits.h> /* for PATH_MAX */ -#include <sys/types.h> /* for opendir(), readdir(), closedir(), stat() */ -#include <sys/stat.h> /* for [l]stat() */ -#include <dirent.h> /* for opendir(), readdir(), closedir() */ -#include <unistd.h> /* for rmdir(), unlink() */ -#include "rmobj.h" - -#define SYSERR strerror(errno) - -int -rmobj(char *obj, char **errmsg) -{ - int ret_val = 0; /* return value from this routine */ - DIR *dir; /* pointer to a directory */ - struct dirent *dir_ent; /* pointer to directory entries */ - char dirobj[PATH_MAX]; /* object inside directory to modify */ - struct stat statbuf; /* used to hold stat information */ - static char err_msg[1024]; /* error message */ - - /* Determine the file type */ - if ( lstat(obj, &statbuf) < 0 ) { - if ( errmsg != NULL ) { - sprintf(err_msg, "lstat(%s) failed; errno=%d: %s", - obj, errno, SYSERR); - *errmsg = err_msg; - } - return -1; - } - - /* Take appropriate action, depending on the file type */ - if ( (statbuf.st_mode & S_IFMT) == S_IFDIR ) { - /* object is a directory */ - - /* Do NOT perform the request if the directory is "/" */ - if ( !strcmp(obj, "/") ) { - if ( errmsg != NULL ) { - sprintf(err_msg, "Cannot remove /"); - *errmsg = err_msg; - } - return -1; - } - - /* Open the directory to get access to what is in it */ - if ( (dir = opendir(obj)) == NULL ) { - if ( rmdir(obj) != 0 ) { - if ( errmsg != NULL ) { - sprintf(err_msg, "rmdir(%s) failed; errno=%d: %s", - obj, errno, SYSERR); - *errmsg = err_msg; - } - return -1; - } else { - return 0; - } - } - - /* Loop through the entries in the directory, removing each one */ - for ( dir_ent = (struct dirent *)readdir(dir); - dir_ent != NULL; - dir_ent = (struct dirent *)readdir(dir)) { - - /* Don't remove "." or ".." */ - if ( !strcmp(dir_ent->d_name, ".") || !strcmp(dir_ent->d_name, "..") ) - continue; - - /* Recursively call this routine to remove the current entry */ - sprintf(dirobj, "%s/%s", obj, dir_ent->d_name); - if ( rmobj(dirobj, errmsg) != 0 ) - ret_val = -1; - } - - /* Close the directory */ - closedir(dir); - - /* If there were problems removing an entry, don't attempt to - remove the directory itself */ - if ( ret_val == -1 ) - return -1; - - /* Get the link count, now that all the entries have been removed */ - if ( lstat(obj, &statbuf) < 0 ) { - if ( errmsg != NULL ) { - sprintf(err_msg, "lstat(%s) failed; errno=%d: %s", - obj, errno, SYSERR); - *errmsg = err_msg; - } - return -1; - } - - /* Remove the directory itself */ - if ( statbuf.st_nlink >= 3 ) { - /* The directory is linked; unlink() must be used */ - if ( unlink(obj) < 0 ) { - if ( errmsg != NULL ) { - sprintf(err_msg, "unlink(%s) failed; errno=%d: %s", - obj, errno, SYSERR); - *errmsg = err_msg; - } - return -1; - } - } else { - /* The directory is not linked; rmdir() can be used */ - if ( rmdir(obj) < 0 ) { - if ( errmsg != NULL ) { - sprintf(err_msg, "rmdir(%s) failed; errno=%d: %s", - obj, errno, SYSERR); - *errmsg = err_msg; - } - return -1; - } - } - } else { - /* object is not a directory; just use unlink() */ - if ( unlink(obj) < 0 ) { - if ( errmsg != NULL ) { - sprintf(err_msg, "unlink(%s) failed; errno=%d: %s", - obj, errno, SYSERR); - *errmsg = err_msg; - } - return -1; - } - } /* if obj is a directory */ - - /* - * Everything must have went ok. - */ - return 0; -} /* rmobj() */ |
