    NAME

    
    
    chdir
    
     
    fchdir
    
     - change current working directory
    
     
    

    LIBRARY

    Lb libc
    
     
    

    SYNOPSIS

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

    DESCRIPTION

    The Fa path argument points to the pathname of a directory. The chdir ();
    system call causes the named directory to become the current working directory, that is, the starting point for path searches of pathnames not beginning with a slash, `/'

    The fchdir ();
    system call causes the directory referenced by Fa fd to become the current working directory, the starting point for path searches of pathnames not beginning with a slash, `/'

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

    RETURN VALUES

    Rv -std  

    ERRORS

    The chdir ();
    system call will fail and the current working directory will be unchanged if one or more of the following are true:

    Bq Er ENOTDIR
    A component of the path prefix is not a directory.
    Bq Er ENAMETOOLONG
    A component of a pathname exceeded 255 characters, or an entire path name exceeded 1023 characters.
    Bq Er ENOENT
    The named directory does not exist.
    Bq Er ELOOP
    Too many symbolic links were encountered in translating the pathname.
    Bq Er EACCES
    Search permission is denied for any component of the path name.
    Bq Er EFAULT
    The Fa path argument points outside the process's allocated address space.
    Bq Er EIO
    An I/O error occurred while reading from or writing to the file system.

    The fchdir ();
    system call will fail and the current working directory will be unchanged if one or more of the following are true:

    Bq Er EACCES
    Search permission is denied for the directory referenced by the file descriptor.
    Bq Er ENOTDIR
    The file descriptor does not reference a directory.
    Bq Er EBADF
    The argument Fa fd is not a valid file descriptor.
