27[1mDESCRIPTION[0m
28       [1mlfc_accessr  [22mchecks  in  the  name server  database
29the existence or the
30       accessibility  of the file replica [4msfn[24m according to
31the bit  pattern  in
32       [4mamode[24m using the real user ID.
33
34       [4msfn[24m    is  either  the  Site  URL  or  the   Physi‐
35cal  File Name for the
36              replica.
37
38       [4mamode[24m   the  bit  pattern  is built by an OR of the
39constants  defined  in
40              <[1munistd.h[22m>  under  Unix  or  to be explicit‐
41ly defined under Win‐
42              dows/NT:
43
44              [1mR_OK   [22mtest for read permission
45
46              [1mW_OK   [22mtest for write permission
47
48              [1mX_OK   [22mtest for search/execute permission
49
50              [1mF_OK   [22mtest for existence of the file.
51
52[1mRETURN VALUE[0m
53       This routine returns 0 if the operation was successful  or
54‐1  if  the
55       operation failed. In the latter case, [1mserrno [22mis set
56appropriately.
