.BI "char *" csumvalue )
.SH DESCRIPTION
.B Cns_setfsizeg
sets the filesize for a regular file having the given GUID; set also the last modification time to the
current time.
This function should only be called by the stager after the last write
operation has been performed on the file.
The file is identified by its
.IR guid .
.TP
.I guid
specifies the Grid Unique IDentifier.
.TP
.I csumtype
specifies the type of checksum. Valid types are:
.RS
.TP
.B CS
standard 32 bits checksum
.TP
.B AD
Adler 32 bits checksum
.TP
.B MD
MD5 128 bits checksum
.RE
.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 EFAULT
.I guid
is a NULL pointer.
.TP
.B EINVAL
The length of the
.I guid
exceeds
.B CA_MAXGUIDLEN
or the length of the
.I csumtype
exceeds 2 or
.I csumtype
is an unknown type or the length of the
.I csumvalue
exceeds 32.
.TP
.B SENOSHOST
Host unknown.
.TP
.B SENOSSERV
Service unknown.
.TP
.B SECOMERR
