NAME
chdir - change current working directory

SYNOPSIS
chdir(path)
const char *path;

DESCRIPTION
Path is the pathname 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. Otherwise, a
value of -1 is returned and errno is set to indicate 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.

[EINVAL] The pathname contains a character with the high-
order bit set.

[ENAMETOOLONG] A component of a pathname exceeded 255 characters,
or an entire path name exceeded 1023 characters.

[ENOENT] The named directory does not exist.

[ELOOP] Too many symbolic links were encountered in
translating the pathname.

[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.
