Synopsis

#include <unistd.h>

int chdir(const char *path);

Status

Partially implemented

Conformance

IEEE Std 1003.1-2017

Description

The purpose is to change working directory. The chdir() function shall cause 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 shall be returned. Otherwise, -1 shall be returned, the current working directory shall remain unchanged, and errno shall be set to indicate the error.

Errors

The chdir() function shall fail if:

  • EACCES - Search permission is denied for any component of the pathname.

  • ELOOP - A loop exists in symbolic links encountered during resolution of the path argument. ENAMETOOLONG

The length of a component of a pathname 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 names an existing file that is neither a directory nor a symbolic link to a directory.

The chdir() function may fail if:

  • ELOOP - More than SYMLOOP_MAX symbolic links were encountered during resolution of the path argument. ENAMETOOLONG

The length of a pathname exceeds PATH_MAX, or pathname resolution of a symbolic link produced an intermediate result with a length that exceeds PATH_MAX.
