NAME
lfc_accessr - check existence/accessibility of a file replica
SYNOPSIS
Under Unix:
#include <sys/types.h>
#include <unistd.h>
#include "lfc_api.h"
Under Windows/NT:
#include <sys/types.h>
#define R_OK 4
#define W_OK 2
#define X_OK 1
#define F_OK 0
#include "lfc_api.h"
int lfc_accessr (const char *sfn,
int amode);
DESCRIPTION
lfc_accessr
checks in the name server database the existence or the accessibility of the
file replica
sfn
according to the bit pattern in
amode
using the real user ID.
- sfn
-
is either the Site URL or the Physical File Name for the replica.
- amode
-
the bit pattern is built by an OR of the constants defined in
<unistd.h>
under Unix or to be explicitely defined under Windows/NT:
-
- R_OK
-
test for read permission
- W_OK
-
test for write permission
- X_OK
-
test for search/execute permission
- F_OK
-
test for existence of the file.
RETURN VALUE
This routine returns 0 if the operation was successful or -1 if the operation
failed. In the latter case,
serrno
is set appropriately.
ERRORS
- ENOENT
-
The named file does not exist.
- EACCES
-
Search 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).
- EFAULT
-
sfn
is a NULL pointer.
- EINVAL
-
amode
is invalid.
- ENAMETOOLONG
-
The length of
sfn
exceeds
CA_MAXSFNLEN.
- SENOSHOST
-
Host unknown.
- SENOSSERV
-
Service unknown.
- SECOMERR
-
Communication error.
- ENSNACT
-
