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.
