.br
\fB#include "Cns_api.h"\fR
.sp
.BI "int Cns_delreplicasbysfn (int " nbfiles ,
.BI "const char **" sfns ,
.BI "const char **" guids ,
.BI "int *" nbstatuses ,
.BI "int **" statuses )
.SH DESCRIPTION
.B Cns_delreplicasbysfn
deletes entries associated with a list of sfns and corresponding lfn if last replica.
An extra check may be obtained by specifying a list of
.IR guids .
.TP
.I nbfiles
specifies the number of file names in the array
.IR sfns .
.TP
.I sfns
specifies either the Site URLs or the Physical File Names for the list of replicas.
.TP
.I guids
specifies the list of Grid Unique IDentifiers (optional). Can be NULL.
.TP
.I nbstatuses
will be set to the number of replies in the array of statuses.
.TP
.I statuses
will be set to the address of an array of integer statuses allocated
by the API. The client application is responsible for freeing the array when not
needed anymore.
Individual statuses are 0 if the operation was successful or set to the
serrno value in case of error.
.SH RETURN VALUE
This routine returns 0 if the operation was successful or -1 if the operation
failed. In the latter case,
.B serrno
is set appropriately.
.SH ERRORS
.TP 1.3i
.B ENOENT

is not strictly positive or the length of one of the
.I guids
exceeds
.BR CA_MAXGUIDLEN .
.TP
.B ENAMETOOLONG
The length of
.I sfn
exceeds
.BR CA_MAXSFNLEN .
.TP
