NAME
chdir, fchdir - change current working directory
SYNOPSIS
#include <unistd.h>
int chdir(const char *path)
int fchdir(int fd)
DESCRIPTION
Path is the pathname of a directory. Fd is the file
descriptor of a directory.
Chdir causes this directory to become the current working
directory, the starting point for path names not beginning
with ``/''.
In order for a directory to become the current directory, a
process must have execute (search) access to the directory.
RETURN VALUE
Upon successful completion, a value of 0 is returned. Oth-
erwise, a value of -1 is returned and errno is set to indi-
cate the error.
ERRORS
Chdir will fail and the current working directory will be
unchanged if one or more of the following are true:
[ENOTDIR] A component of the path prefix is not a
directory.
[ENAMETOOLONG] The path name exceeds PATH_MAX characters.
[ENOENT] The named directory does not exist.
[ELOOP] Too many symbolic links were encountered in
translating the pathname. (Minix-vmd)
[EACCES] Search permission is denied for any component
of the path name.
[EFAULT] Path points outside the process's allocated
address space.
[EIO] An I/O error occurred while reading from or
writing to the file system.
