# NAME

fd_chdir - change working directory

# SYNOPSIS

    #include <limb/djbunix.h>

```pre hl
int fd_chdir(int <em>fd</em>)
```

# DESCRIPTION

The `fd_chdir`() function is a safe wrapper around [fchdir](3), i.e. it cannot
be interrupted by signals. More precisely, if [fchdir](3) fails with *EINTR* it
is automatically called again until it succeeds or fails with another error.

# RETURN VALUE

On success, the `fd_chdir`() function return 0. Otherwise, it returns -1 and
sets `errno` to indicate the error.

# ERRORS

The `fd_chdir`() function may fail and set `errno` for any of the errors
specified for [fchdir](3) except *EINTR*.
