chdir, fchdir - change working directory


#include <unistd.h> int chdir(const char *path); int fchdir(int fd);


chdir() changes the current working directory to that specified in path. fchdir() is identical to chdir(); the only difference is that the directory is given as an open file descriptor.


On success, zero is returned. On error, -1 is returned, and errno is set appropriately.


Depending on the file system, other errors can be returned. The more general errors for chdir() are listed below: EACCES Search permission is denied for one of the directories in the path prefix of path. (See also path_resolution(2).) EFAULT path points outside your accessible address space. EIO An I/O error occurred. ELOOP Too many symbolic links were encountered in resolving path. ENAMETOOLONG path is too long. ENOENT The file does not exist. ENOMEM Insufficient kernel memory was available. ENOTDIR A component of path is not a directory. The general errors for fchdir() are listed below: EACCES Search permission was denied on the directory open on fd. EBADF fd is not a valid file descriptor.


A child process created via fork(2) inherits its parent's current work- ing directory. The current working directory is left unchanged by execve(2). The prototype for fchdir() is only available if _BSD_SOURCE is defined, or _XOPEN_SOURCE is defined with the value 500.
