NAME

chdir - change working directory

 SYNOPSIS

#include <unistd.h>

int chdir(const char *path);

 DESCRIPTION

The chdir() function causes the directory named by the pathname pointed to by the path argument to become the current working directory; that is, the starting point for path searches for pathnames not beginning with /.

 RETURN VALUE

Upon successful completion, 0 is returned. Otherwise, -1 is returned, the current working directory remains unchanged and errno is set to indicate the error.

 ERRORS

The chdir() function will fail if:

[EACCES]

Search permission is denied for any component of the pathname.

[ELOOP]

Too many symbolic links were encountered in resolving path.

[ENAMETOOLONG]

The path argument exceeds {PATH_MAX} in length or a pathname component is longer than {NAME_MAX}.

[ENOENT]

A component of path does not name an existing directory or path is an empty string.

[ENOTDIR]

A component of the pathname is not a directory.

The chdir() function may fail if:

[ENAMETOOLONG]

Pathname resolution of a symbolic link produced an intermediate result whose length exceeds {PATH_MAX}.
