closedir, wclosedir

Header File

Category
Directory Control Routines
Prototype
void closedir(DIR *dirp);
void wclosedir(wDIR *dirp);
Description
Closes a directory stream.
closedir is available on POSIX-compliant UNIX systems.
The closedir function closes the directory stream dirp, which must have been opened by a previous call to opendir. After the stream is closed, dirp no longer points to a valid directory stream.
wclosedir is the Unicode version of closedir.
Return Value
If closedir is successful, it returns 0. Otherwise, closedir returns -1 and sets the global variable errno to
EBADF |
The dirp argument does not point to a valid open directory stream |
Example
/* opendir.c - test opendir(), readdir(), closedir() */ #include <dirent.h> #include <stdio.h> #include <stdlib.h> void scandir(char *dirname) { DIR *dir; struct dirent *ent; printf("First pass on '%s':\n",dirname); if ((dir = opendir(dirname)) == NULL) { perror("Unable to open directory"); exit(1); } while ((ent = readdir(dir)) != NULL) printf("%s\n",ent->d_name); printf("Second pass on '%s':\n",dirname); rewinddir(dir); while ((ent = readdir(dir)) != NULL) printf("%s\n",ent->d_name); if (closedir(dir) != 0) perror("Unable to close directory"); } void main(int argc,char *argv[]) { if (argc != 2) { printf("usage: opendir dirname\n"); exit(1); } scandir(argv[1]); exit(0); }
