CHDIR(2)                                                              CHDIR(2)



NAME
       chdir - change current working directory

SYNOPSIS
       chdir(path)
       char *path;

DESCRIPTION
       _P_a_t_h  is  the  pathname of a directory.  _C_h_d_i_r causes this directory to
       become the current working directory, the starting point for path names
       not beginning with ‘‘/’’.

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

RETURN VALUE
       Upon successful completion, a value of 0  is  returned.   Otherwise,  a
       value of -1 is returned and _e_r_r_n_o is set to indicate the error.

ERRORS
       _C_h_d_i_r  will fail and the current working directory will be unchanged if
       one or more of the following are true:

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

       [EINVAL]       The pathname contains a character  with  the  high-order
                      bit set.

       [ENAMETOOLONG] A component of a pathname exceeded 255 characters, or an
                      entire path name exceeded 1023 characters.

       [ENOENT]       The named directory does not exist.

       [ELOOP]        Too many symbolic links were encountered in  translating
                      the pathname.

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

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

       [EIO]          An  I/O  error occurred while reading from or writing to
                      the file system.
