18       [1mlfc_readlink [22mreads the value of a symbolic link  in

20
21       [4mpath[24m   specifies the link name relative to the cur‐

23              the full LFC pathname.
24
25       [4mbuf[24m    points at a buffer to receive the value.
26
27       [4mbufsiz[24m gives the buffer size.
28
29[1mRETURN VALUE[0m
30       This routine returns the number of characters put  in  the
31buffer if  the
32       operation   was  successful or ‐1 if the operation failed.
