.SS Description
.PP
Allows sending parameter data to the server in pieces (or chunks),
e.g.\ if the size of a blob exceeds the size of max_allowed_packet size.
This function can be called multiple times to send the parts of a
character or binary data value for a column, which must be one of the
\f[C]TEXT\f[R] or \f[C]BLOB\f[R] datatypes.
.SS Parameter
.IP \[bu] 2
\f[C]stmt\f[R] \- a statement handle, which was previously allocated by
\f[B]mysql_stmt_init(3)\f[R].
.IP \[bu] 2
\f[C]param_no\f[R] \- indicates which parameter to associate the data
with.
Parameters are numbered beginning with 0.
.IP \[bu] 2
\f[C]data\f[R] \- a buffer containing the data to send.
.IP \[bu] 2
\f[C]long\f[R] \- size of the data buffer.
.SS Return value
.PP
Returns zero on success, nonzero if an error occurred.
.SS Notes
.IP \[bu] 2
\f[C]mysql_stmt_send_long_data()\f[R] must be called before
\f[B]mysql_stmt_execute(3)\f[R].
.IP \[bu] 2
bound variables for this column will be ignored when calling
\f[B]mysql_stmt_execute(3)\f[R].
