SYNOPSIS
#include <sys/types.h>#include "lfc_api.h"
struct lfc_linkinfo *lfc_listlinks (const char *path, const char *guid, int flags, lfc_list *listp)
DESCRIPTION
lfc_listlinks lists link entries for a given file. The first entry in the list is the actual file name, while the other entries are the symbolic links pointing at this file.- path
- specifies the logical pathname.
- guid
- specifies the Grid Unique IDentifier.
- flags
-
may be one of the following constant:
-
- CNS_LIST_BEGIN
- the first call must have this flag set to allocate buffers and initialize pointers.
- CNS_LIST_CONTINUE
- all the following calls must have this flag set.
- CNS_LIST_END
- final call to terminate the list and free resources.
-
RETURN VALUE
This routine returns a pointer to a structure containing the current link entry if the operation was successful or NULL if all entries have been returned or if the operation failed. In the latter case, serrno is set appropriately.ERRORS

- EFAULT
- path and guid are NULL pointers or listp is a NULL pointer.
- ENOTDIR
- A component of path prefix is not a directory.
- EINVAL
- The length of guid exceeds CA_MAXGUIDLEN or path and guid are both given and they point at a different file.
- ENAMETOOLONG
- The length of path exceeds CA_MAXPATHNAMELEN.
- SENOSHOST
- Host unknown.
- SENOSSERV
- Service unknown.
