CHDIR(2) — UNIX Programmer’s Manual
NAME
chdir − change current working directory
SYNOPSIS
chdir(path)
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.
