Under Windows/NT:

[1mdpns_accessr [22mchecks in the name server database the existence or the
accessibility of the file replica [4msfn[24m according to the bit pattern in
[4mamode[24m using the real user ID.

[4msfn[24m is either the Site URL or the Physical File Name for the

[4mamode[24m the bit pattern is built by an OR of the constants defined in
<[1munistd.h[22m> under Unix or to be explicitly defined under Win-

[1mR_OK [22mtest for read permission

[1mW_OK [22mtest for write permission

[1mX_OK [22mtest for search/execute permission

[1mF_OK [22mtest for existence of the file.

This routine returns 0 if the operation was successful or -1 if the
operation failed. In the latter case, [1mserrno [22mis set appropriately.

[1mENOENT [22mThe named file does not exist.

[1mEACCES [22mSearch permission is denied on a component of the parent
file prefix, the specified access to the file itself is
denied or W_OK is requested but the replica status is not
'P' (cannot modify an existing file).

[1mEFAULT [4m[22msfn[24m is a NULL pointer.

[1mEINVAL [4m[22mamode[24m is invalid.

[1mENAMETOOLONG [22mThe length of [4msfn[24m exceeds [1mCA_MAXSFNLEN[22m.

[1mSENOSHOST [22mHost unknown.

[1mSENOSSERV [22mService unknown.

[1mSECOMERR [22mCommunication error.

[1mENSNACT [22mName server is not running or is being shutdown.
