NAME

chdir − change current working directory

USAGE

chdir(path) char *path;

DESCRIPTION

Chdir sets path, which must be the name of a directory, as the current working directory.  This becomes the starting point for resolving pathnames not beginning with a slash (/). 

In order for a directory to become the current directory, a process must have execute (search) access to the directory. 

RETURN VALUE

A successful chdir returns zero.  Otherwise, it returns -1 and sets errno as indicated below. 

ERRORS

Chdir will fail and the current working directory will not change if one or more of the following are true:

[ENOTDIR] A component of the pathname is not a directory. 

[ENOENT] The directory named does not exist. 

[ENOENT] The argument pathname is too long. 

[EPERM] The argument contains a byte with the high-order bit set. 

[EACCES] Search permission is denied for any component of the pathname. 

[EFAULT] Path points outside the process’s allocated address space. 

[ELOOP] The call encountered too many symbolic links in translating the pathname.
