lfc_getreplicas \- get the replica entries associated with a list of GUIDs

.sp
.BI "int lfc_getreplicas (int " nbguids ,

.SH DESCRIPTION
.B lfc_getreplicas
gets the replica entries associated with a list of GUIDs.
.TP
.I nbguids
specifies the number of guids in the array
.IR guids .
.TP
.I guids
specifies the list of Grid Unique IDentifiers.
.TP
.I se
allows to restrict the replica entries to a given SE.
.TP
.I nbentries
will be set to the number of entries in the array of replicas.
.TP
.I rep_entries
will be set to the address of an array of lfc_filereplicas structures allocated
by the API. The client application is responsible for freeing the array when not
needed anymore.

Memory could not be allocated for marshalling the request or unmarshalling
the reply.
.TP
.B EFAULT
.IR guids ,
.I nbentries
or
.I rep_entries
is a NULL pointer.
.TP
.B EINVAL
.I nbguids
is not strictly positive, the length of one of the
.I guids
exceeds
.B CA_MAXGUIDLEN
or the length of
.I se
exceeds
.BR CA_MAXHOSTNAMELEN .
