    NAME

    chdir, fchdir - change working directory
     
    

    SYNOPSIS

    #include <unistd.h>

    int chdir(const char *path);
    int fchdir(int fd);

    Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

    fchdir(): _BSD_SOURCE || _XOPEN_SOURCE >= 500  

    DESCRIPTION

    chdir() changes the current working directory of the calling process to the directory specified in path.

    fchdir() is identical to chdir(); the only difference is that the directory is given as an open file descriptor.  

    RETURN VALUE

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

    ERRORS

    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 components of path. (See also path_resolution(7).)
    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.
     

    CONFORMING TO

    SVr4, 4.4BSD, POSIX.1-2001.  

    NOTES

    The current working directory is the starting point for interpreting relative pathnames (those not starting with aq/aq).

    A child process created via fork(2) inherits its parent's current working 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.
