[1mlfc_access [22mchecks in the name server database the existence or the
accessibility of the file/directory [4mpath[24m according to the bit pattern
in [4mamode[24m using the real user ID.
[4mpath[24m specifies the logical pathname relative to the current LFC
directory or the full LFC pathname.
[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 directory/file.
This routine returns 0 if the operation was successful or -1 if the
operation failed. In the latter case, [1mserrno [22mis set appropriately.

prefix or specified access to the file itself is denied.
[1mEFAULT [4m[22mpath[24m is a NULL pointer.
[1mENOTDIR [22mA component of [4mpath[24m prefix is not a directory.
[1mEINVAL [4m[22mamode[24m is invalid.
