rmdir - Remove a directory file
#include <unistd.h>
int rmdir(
const char *path );
Interfaces documented on this reference page conform to
industry standards as follows:
rmdir(): XSH4.0, XSH4.2, XSH5.0
Refer to the standards(5) reference page for more information
about industry standards and associated tags.
Specifies the directory pathname. The final component of
the path parameter cannot be a symbolic link.
The rmdir() function removes the directory specified by
the path parameter. The directory is removed only if it
is an empty directory.
For the rmdir() function to execute successfully, the
calling process must have write access to the parent
directory of the path parameter with respect to all of the
system's access control policies.
If the directory's link count becomes 0 (zero) and no process
has the directory open, the space occupied by the
directory is freed and the directory is no longer accessible.
If one or more processes have the directory open when
the last link is removed, the . (dot) and .. (dot-dot)
entries, if present, are removed before the rmdir() function
returns, and no new entries may be created in the
directory. However, the directory is not removed until all
references to the directory have been closed.
Upon successful completion, the rmdir() function marks the
st_ctime and st_mtime fields of the parent directory for
update.
Upon successful completion, the rmdir() function returns a
value of 0 (zero). If the rmdir() function fails, a value
of -1 is returned and errno is set to indicate the error.
If the rmdir() function fails, the directory is not
deleted and errno may be set to one of the following values:
Search permission is denied on a component of the
path parameter, or write permission is denied on the parent
directory of the directory to be removed. The process
does not have write access to the parent directory with
respect to one of the system's access control policies.
The directory is in use as either the mount point for a
file system or the current directory of the process that
issued the rmdir() function. The directory named by the
path parameter is not empty. The path parameter is an
invalid address. While reading from or writing to the
file system, an I/O error occurred. Too many links were
encountered in translating path. The length of the path
parameter exceeds PATH_MAX, or a pathname component is
longer than NAME_MAX. The directory named by the path
parameter does not exist or is an empty string. A component
of the path parameter is not a directory. The
S_ISVTX option is set on the parent directory of the
directory to be removed, and the caller is not the file
owner. The directory named by the path parameter resides
on a read-only file system.
[Tru64 UNIX] For NFS file access, if the rmdir() function
fails, errno may also be set to one of the following values:
The file position pointer associated with the filedes
parameter was negative. Indicates either that the system
file table is full, or that there are too many files currently
open in the system. Indicates a stale NFS file
handle. An opened file was deleted by the server or
another client; a client cannot open a file because the
server has unmounted or unexported the remote directory;
or the directory that contains an opened file was either
unmounted or unexported by the server.
