+
+# NAME
+
+sareadlinkat - read the content of a symbolic link
+
+# SYNOPSIS
+
+    #include <limb/djbunix.h>
+
+```pre hl
+int sareadlinkat(stralloc *<em>sa</em>, int <em>fd</em>, const char * restrict <em>file</em>)
+```
+
+# DESCRIPTION
+
+The `sareadlinkat`() function places the content of the symbolic link referred
+to by `file` in the stralloc `sa`.
+
+The symbolic link whose content is read is relative to the directory associated
+with the file descriptor `fd`. If passed the special value `AT_FDCWD` in the
+`fd` parameter, the current working directory is used.
+
+For more details, refer to [`readlinkat`](3).
+
+# RETURN VALUE
+
+Upon successful completion the function returns 0. Otherwise it returns -1 and
+sets `errno` to indicate the error.
+
+# ERRORS
+
+This function may fail if:
+
+: *ENOMEM*
+:: Insufficient memory available to grow `sa`
+
+This function may also fail and set `errno` for any of the errors specified for
+the function [`readlinkat`](3).
